When you get kicked from single player (for example, do /tp @p ~ ~10000000000000000 ~ it will kick you.) When you click Back to title screen, it won't send you to the title or singleplayer world select screens. It sends you to the Multiplayer screen. Who'd play single player, get kicked off, and go join a server on accident?
