Well, as I've stated here and in other places across the web, just because Aura acts like Halo energy shields doesn't mean it's free from basic physics. I liken it to an invisible supporting structure to the body, greatly enhancing durability and speeding up the healing process. However, being an energy-based projection from the user's own soul, it is a finite resource in the heat of combat.

In practice, Aura is more like Ki than shielding in that the user can still suffer from debilitating blows and effects that focus less on brute force, and more on technique. For example, when Yang fought Neo, the small tyke easily took her out with precise, measured hits that depleted her Aura and knocked her out extremely quickly, when even mech suits with enough power to shatter concrete failed to do so, all because of technique and the opposing force in question.

Shielding doesn't prevent physics-based loopholes like chokeouts and recoil patterns, so I don't assume Aura is free from it either. It seems to be more of a protection of the physical body, albeit one that can be focused like Ki.
