As the command person for the world he is talking about I can give a little more detail.
To prevent the world file size from growing too large I set up command blocks to teleport players back the spawn area if they walked 10k blocks out an any direction from spawn. Upon this update the commands from that command block no longer just effect the overworld they also transfer over to the nether dimension, and possibly the End dimension. There is the equivalent of 10k blocks (in the overworld) in the in either direction in the nether as well.
We are running a world that has what we call “Vaults” which are bedrock boxes that have command blocks on them to run the spread player command if the vault is set to “private” or to set the player to adventure if the vault it set to “protected” creating a version of plots in bedrock edition. These commands also transfer over dimensions along with the functions used for the commands, making the nether unusable due to being randomly teleported, or being put into adventure mode.
