Signed in to two accounts on Xbox, played on account 1.

Died on account 1, then exited server.

Switched to account 2 via the Xbox menu, then went into the DayZ servers menu.

Switched back to account 1, and joined the original server using the “Join game” tab on my friend’s Xbox profile.

Spawned into the original server, next to where I died, with all of the loot I had when I died.
