What's so hard to understand. In any sport the final is the final. Your past performances don't matter. Who you beat earlier on doesn't matter. You need to win the final to win the tournament.
So the double elimination element is a way to narrow down a large field to the two teams that compete in the final. If you win all your games, great, then you get a place in the final. The other place is given to the team who only loses once. Now both teams are in the final and the winner wins the tournament.
If you are looking for a fairer way to decide the winner, then stick with league style round robin, with no finals system. Much fairer, but not as exciting for a tournament.
