Since we don't really know that much about Aura, your theory seems rather plausible. That and the fact that Adam pulled out his huge move, (i think Monty called it "Moonslice") and it seems like it's a very powerful thing. His sword also has the ability to absorb power/energy, so I'm guessing with those factored in, it would make sense for Yang's hand to go off in one clean slice even if she had full aura.
