Ask yourself the importance of Game2 in the current sets.
If I won Game1, I have a strong advantage going into Game3. Game2 is less important that I win. While still fine and dandy if I do, it's not of vital importance I don't drop that game.
In a flipped system, if I won Game1, I don't have an advantage going into Game3. Game2 is far more important that I try and win. If I don't win this, I'm far more likely to lose the set. Of course I won't want to drop game2.
On the flip side.
If I lose Game1, Game2 is my everything. But even if I win it - I go into Game3 with a disadvantage. While possible, it's just less likely I can redeem myself.
Flipped system:
If I lost game 1, just like the current system Game2 is my everything. But if I win it - I have a shot at redeeming myself on neutral grounds. While possible I won't, it's far more likely.
The flipped system takes the weight off of Game1 - and this is for a reason. It's so that each player has an equal opportunity to prove they are skilled.

The winning example is a stronger support than the losing example.
Our counterpick systems broken, most people recognize this, and many want to take that weight off of Game1. I've sandbagged and thrown a few Game2's so that my opponent can't adapt to me. I then hard CP them in both character and stage and make quick work of them. =\ Even I abuse the current system.
