I think you are right, because I read something very close or exact this. At the help section. But I read something in facebook options/configuration or in top eleven web/game about cancelling the "account of top eleven". I am pretty sure I read something about cancelling acount top eleven but I couldn't be sure about its meaning. Maybe once you cancel this option that I read, you have to wait also about 70 days to let you enter again at top eleven with your same FaceBook account.
