I'm in my prime.
No, Combos Are Hard has to be the only action. If you use it with Double-Take (which is Setsuki's, by the way), it just doesn't do anything.
Thanks for the answer and the correction. My nine-year old was playing Setsuki and figured out that combination. I thought it was probably illegal, but since it was her first game and she figured it out herself, I let her go ahead and do it.
