So when I play ranked tag matches online, I noticed that sometimes I would fight against two people using their own gamer tags as opposed to [Gamertag](1). I play with my brother in ranked tag matches as a guest most of the time. So how do these people play on the same 360 with separate gamer tags? Just recover your account on the 360 you're playing on? Also when you play tag matches with 2 separate gamer tags, does the person who recovered (if that's how it works) their tag get credit to their statistics?
