It will only show one name at the end. If you swap tabs, it will add the same name again. If you keep doing it, it will keep adding it, until it looks like the image in the picture I posted. I haven't checked to see if there is a limit, but I don't think there is.
The name itself might be random, or might have something to do with who enters the lobby when you do. Last time, it was my own name.
