Teleport by relogging while in lava

I logged out while i was dying in lava in a cave in the overworld. I copied the world, so I could try to get out of the lava multiple times. However, this was not needed. Of the 3 times I opened the world (2 copied versions), I spawned 2 times in the cave near the position where i was in the lava and 1 time on the ground above. I was at full health, which I wasn't when I logged out and in a different position. The zipped minecraft world shows you it with the lava on 40, 11, -5.
