At the moment when a game room is created, its creator is auto-joined so that he can wait for the other (or others) player(s)
This is done because usually the guy who starts a game room is the one who also wants to play. If we don't autojoin him in the game room he will not be 100% sure to play.
Let's say a user creates a game room for 2 players, but he doesn't join it.
Maybe two other players with faster reflexes and connections may enter the room and start playing, leaving the creator out. (He would have to create a new room again)
A possible solution to this is to allow the room creator to stay in both rooms (the current one and the new game room). This way he could still interact in the old room while keeping his player slot occupied, so no one else can get it.
This option is already supported by the server but I am quite sure it's not yet implemented in the API. We didn't implement it because we thought this would be a pretty rare case... but maybe you proved us wrong!
Activating this new feature wouldn't take too much time and if you're interested we can implement it in the next days and send you a new version of the API, meanwhile we'll do some more tests and we'll publish the new stable API as soon as they're enough tested.
Also I'd like to know better how your application is supposed to work, maybe I could suggest some other ways to get to the same result.
