If quickly leaving when loading the end you are teleported to the end islands

this was in java minecraft realms

While i was loading into the end after going through the portal for the first time, I left because I was scared that I would fall off during the black screen that was showing. I then rejoined and was spawned inside of one of the islands of the end realm accessed after beating the dragon, and dug and built up till I was at the surface. I was at 0 50 0 when I spawned, and I spawned next to a city with an eyltra.
