Something wrong with your logic.
For a particular game, your thinking maybe right. However, you are playing 3 games!! And can you sure you can do well in the other games? If no, even you are winning, those players are still your opponents overall. Therefore, run as far as away, beat your opponents as much as you can, which is more safety :p
And that is why I make Top 6 seeded and give their advantages, also create winning or losing pool in semi - final. Therefore even you are winning you also wish to make other players score less:p, but not only qualify.
