Is this connected? I hope not

[betterlate1]

Was in game..someone on chat asked me to play told him was in game..wanted to see his stats..so clicked his name and learned an invite was sent..same time person I was playing (almost start of game) was gone.and game ended. Hope they are not connected. So how do you see stats if there is automatically an invite sent ? and was it connected to game ending and person leaving? Thanks.
