The basic idea behind SLI AA is that one GPU is used to render the game, the other GPU is there to just perform anti aliasing. They are working together to give you a final product, but they do different tasks unlike AFR SLI where both cards are sharing a common workload.
So the only catch is that one GPU might be working at full speed to render the game, and the other one might only be working at half speed to do AA.
