There is a winner brackets and a loser brackets.
If you lose from the winner brackets, you will be moved down to the loser brackets.
If you lose from the loser brackets, you are out of the tournament.
In the end if you win round 10 in the loser brackets final, you will be moved up to winner brackets for round 11.
If the player from the winner brackets win the first finale in round 11, the tournament is over.
if the player from the loser brackets win the first finale in round 11, a new finale will be played in round 12 (as all players can loose one game without loosing the tournament. Then the winner of finale in round12 will win the tournament.
Hope this explains, and also make it pretty clear that its a good idea to stay in the winner brackets if possible
