This happens to me a LOT when I duel:
- When engaged in PvP, I jump constantly because I've found that it helps prevent falling off the edge of the world.
- While doing this, often times I get killed in mid air (nothing wrong with that, it actually looks very dramatic).
- About 3/5 times it happens I get teleported back to the point I was killed at (the system sends me where I should've landed in the first place), right when I (re)load in the DR. It doesn't happen that often when in the living realm but it's happened too (ulber chews, zhai dies, immediately comes back, ulber chews again... kinda like bulimia only backwards).
There is little I can do to prevent or promote the teleportation, so there's no way to actually exploit this bug other than being lucky. However, it's worth mentioning.
