My theory is that it deflects damage taken back at the person who inflicted it. Aura normally acts as a forcefield that protects the user, but we've never seen anyone actually take damage from hitting it like when Cardin punches Jaune. Rather than simply softening blows, for Jaune I think it reflects them back at the opponant. This would fit with the defensive semblance he's been stated to have, and is consistant with everything we've seen.

As for the healing: aura does that already, but most of all I think it was probably just a continuity error. Different people probably animated the fight with the Ursa Major than the non-combat scenes that took place before and after. The ones who animated the fight probably forgot to add the wounds to the model. This also explains why the wounds come back after the fight is over. It's not like this show is any stranger to minor continuity errors.
