Like O_Bear said there's a difference.
At week 1 and 9 one of them has to be home game, another away. With both games away on those weeks every team with this schedule loses $$.
Yes, if you are only looking for weeks 1 and 8, but looking at the whole season
... "winning" in weeks 3, 9 and 11 ...
you are winning in weeks 1, 3 and 9 because of two home games.
