People can have similar Semblances. Adam, hypothetically, would be to absorb damage blocked by his Aura to cause more damage. Yang's is to cause more damage the more damage she has taken...if she survives it of course.

So I feel it's along the lines of Adam not being capable of ignoring Aura or cutting through anything, but that he stored so much energy that, when combined with his strength and skill, allows him to pretty much KO everything, dealing more damage than Yang's Aura was capable of resisting.

In RPG terms: Your HP is 40, you have a magic shield that blocks up to 120 damage. You receive 300 damage.
