Actually he said it feels like he's using his aura to amplify hers; given a Semblance is a manifestation of Aura unique to the individual (unless you're a Schnee) that is exactly what he is describing. His Semblance allows him to amplify, and it seems restore, aura.

Given Ren and Nora seemed surprised he was able to do it, the fact that he can makes it pretty obvious that's not a normal ability people have with just their Aura. That means it is definitely his Semblance. In fact, the effects even seemed to linger after he stopped healing her because she was able to summon the Queen Lancer in a matter of seconds whereas attempting to summon her Knight before took her MUCH longer.

Miles and Kerry also outright stated during a RWBY Rewind episode that it is in fact his semblance; I think they referred to it as Aura Amplification or something along those lines.
