When I play minecraft with my brother, we use split screen on the Xbox. But when the person using the 2nd section of the split screen dies and the world has immediate respawn, it sometimes takes a long time or it never generates the world. The person using the first screen always has to log off and then join back in for it to work again. But this does not effect the first person. The first person's screen is just fine, he spawns whenever he is supposed to.
