Correct me if I'm wrong, but doesn't the feat say that you can move up to your speed on a success? It seems to suggest that there is no cost to taking said movement, which means that you could feint, move away, and then use your move action in any manner which you deem fit (whether that be moving your base speed again, or doing something else that uses a move action... like another feint.)
If this is the case, I think this may actually be the intended use.
