I thought the same thing, but after watching my clowns get pushed (without swimming) clear across the tank until they hit the next line of current I figured it was ok. It's actually a game to them I think. They will swim against the current and then stop, allowing it to blow them back.
I have my two return lines coming up over my overlow on each side, and then each one is split in a "Y", two blowing behind my rocks and the other two blowing down on the rocks. Then my PHs are on each side (toward the back) and I have them pointing to the center of the front glass. So far that seems to work pretty well.
