As to the recoil thing, it personally reminded me of DBZ (hear me out here). Okay, when Goku was fighting Freeza he used a kamehameha to push himself backwards out of the way of Freeza's blast. Yet (to my knowledge) that is the only time he does that manuver in the entire anime. So we have to assume that that kamahameha's that he fires out can only be as strong as he can withstand, in other words he's strong enough to completely absorb all the recoil from the blast, and in that instance he allowed the recoil to push him backwards. I would assume that Ruby and Yang's recoil on their weapons works the same way. They're strong enough to absorb the recoil when it suits them, but if they want the recoil to push them around they'll let it do so. Did that help?
