Miles and Kerry explained in an interview that Yang losing her arm was from Adam's attack simply doing a lot of damage.

Miles: The Aura is, y'know it's like, we establish in the [...] tournament fights that, like... Yeah, every hit can drop it and some hits can break it. It just so happens that Adam's attack was so badass that, in one hit, it managed to break it and do damage all at once, it was super powerful.

Kerry: Yang had also been fighting off-screen.

Miles: Yeah, exactly. Yeah, that girl, that girl had been through some things! It's not necessarily a sword thing, more just like "Oh, he's strong! Oh, he's a scary man!"

So, basically, Yang didn't have 100% Aura, and the amount she had left wasn't enough to block the entirety of the damage he dealt.
