Why Nether Portals Hijack Each Other
When you step through a portal, Minecraft divides your Overworld coordinates by 8 ($X/8, Z/8$) and searches a horizontal radius of 16 blocks in the Nether (or multiplies by 8 and searches 128 blocks in the Overworld).
Crucially, the game picks the closest portal using 3D Euclidean distance ($X, Y, Z$). If a portal on the Nether roof ($Y=128$) is closer in 3D space than a portal on the Nether floor ($Y=30$), players will be redirected and trapped on the roof!
