Very interesting. Like bi-wing plane designs evolved into mono-wing designs? Perhaps these critters used all four limbs for flight because they had not evolved enough strenght and power to generate lift with just one pair of limbs.

I suspect their (somewhat) immediate ancestors did not have powered flight but instead used assisted gliding.

Full Disclosure: That's cool as far as it goes, but then you need *retrograde* evolution of the hind limbs back into legs as the front wings get stronger.
