I have a nether portal set up at my base in the overworld and when I get into the nether it takes it me to coordinate 78, 82, 15.
I set up another nether portal in the overworld at coordinate -351, 27, -711 and when I went through, it took me straight to 78, 82, 15 in the nether which is where my base portal takes me to so when I went back through the portal I ended up back at my base.
I got the hotfix that said this issue was taken care of but in my case apparently it wasnt

Not sure how to upload the copy from my xbox to my computer but i just uploaded some screenshots, you can see the two overworld coordinates and both shots of the nether are from going through both overworld portals, so both overworld portals send me to the same spot in the nether, and the one portal in the nether only sends me to the portal at 610, 71, 118 in the overworld
@unknown: Could you provide the world seed, then? I might be able to recreate the problem with just the seed and the coordinates given in your screenshots. BTW, try removing that water from the overworld portal to see if that has any effect.
Same problem happening on my realm. It was fixed when a hotfix for 1.13 came out but reverted back in one of the next updates. Seed number 35992756
Although the portal in the nether at 78 82 15 is > 128 blocks away from the "perfect" coordinates that would match the overworld portal at -351 27 -711 (= -43 27 -88), each coordinate separately is within 128 blocks. Bedrock Edition may use a cuboid for range testing/linking where Java uses a sphere, and the wiki only describes Java behavior. There are a lot of game mechanics like this (a lot where Bedrock uses cuboid while Java uses sphere, and a lot where the wiki describes Java only without saying so). Edit: I was conflating the search range with the calculation of nearest portal.
Above, when I said that an overworld portal at -351, 27, -711 should not be able to link to a Nether portal at 78, 82, 15, I must have made a math error. GoldenHelmet's comment made me check again, and indeed the Nether portal is within range, which means that the game is working as intended and this is not a bug.
Each nether portal has a corresponding range it can send you to in the opposite dimension. The range can be calculated by applying the scale factor of 8. When going from the Overworld to the Nether, you divide by the scale factor; when going from the Nether to the Overworld, you multiply instead. Then you add and subtract 128 to each of the scaled X and Z coordinates to get a range for each one. For instance, if the X coordinate for a portal in the overworld is 610, you divide by 8 to get 76 (rounded), then add and subtract 128 to get the range -52..204. Putting the X and Z ranges together with the Y range, which is always 0 to the build height, gives you a cuboid in the destination dimension that the game will search for a portal. If it finds one, it sends you there. If it doesn't find one, it will generate a portal as close as possible to the scaled coordinates. (I'm not certain, but if it finds multiple portals within the search range, I think it sends you to the nearest one.)
Here are the search ranges for each of your portals:
Dimension | Portal Coords | Search Range |
Overworld | -351, 27, -711 | -172..84, 0..127, -216..40 |
Overworld | 610, 71, 118 | -52..204, 0..127, -113..143 |
Nether | 78, 82, 15 | 496..752, 0..255, -8..248 |
As you can see, the X and Z coordinates of your Nether portal are within the search ranges of each of your Overworld portals. However, only the second Overworld portal's X and Z coordinates are within the search range of your Nether portal, so that's the only portal it will send you to.
If you want a second portal in the Nether that reliably links to the first Overworld portal (in the list above), here's what you need to do: First scale the Overworld coordinates to their corresponding Nether coordinates (by dividing by 8). Then, go to the Nether and travel to those coordinates. Build a portal as close to those coordinates as you can. (It doesn't have to be really close, just closer than the first one you built in the Nether.) The new portal should reliably link to your Overworld portal, and the other Overworld portal and its paired Nether portal should be unaffected.

I believe i have a similar issue and have managed to record a clip of it happening. The issue seems to be the nether portal it put's you out (going from overworld -> nether) at is the exact same co ordinates as in the overworld.
Is this the same as the issue reported here?
Luke Dyte: what you are describing is tracked at MCPE-115933.
Would you please verify that you have all the signs right on your coordinates? The overworld coordinates -351, 27, -711 correspond to nether coordinates -44, 27, -89. The distance from there to your nether-side portal is over 160 blocks. It should not be possible for the game to link to an overworld portal to one more than 128 blocks away from its "perfect" nether coordinates.
If you have all the signs correct, it would be very helpful if you were able to upload a copy of your world.
