Once 1 player disconnects, you get a pop up window with the list of users and you get to eject who you want. usually when you get this window, the game is over since you have to eject everyone for the game to continue. You can't just eject 1 player, the game will still be on that window waiting for you to disconnect everyone.
Even though you see the other player's ping and you know they are still connected to you. Eventually everyone will disconnect tired of waiting at that window.
