Perhaps I wasn't clear, but it does take two vine placements to replicate this setup, but the moment you try to collect them, you only get one. I'll update the video accordingly. As you will see, the amount of vines in my hotbar is 17 vines, when I place them it goes down to 15, and when I break and collect them it goes up to only 16. This could be an intentional mechanic for whatever reason, however I highly doubt that randomly deleting a player's vines due to poor placement was a purposeful in-game feature.
