If you call lines appropriately, you will prevent your partner from playing serves that are close, but out. There is no more "optimal" way to win than to not have to hit an out shot.
I agree that the best doubles position is to prepare for the poach when you have a line judge. Otherwise, you have to make those calls, and make them correctly. To do this you have to be on that line. It is easy to take a step or two up after you know the serve is good.
