Yes it still works, but that is quite normal and fine, actually. The game's lobbies/sessions are based on peer-to-peer, so obviously when you cut connections to other players you will get to play by yourself (in other words, you are just "kicking" yourself out of the current session). Someone could join your "solo" session at any time, it just isn't very likely, as the game's services usually find more populated sessions for everyone.

Then again, nowadays you can play the game without restrictions in invite-only and friends sessions, too.
