It is most likely the power behind the hit causes her power to increase as well. Getting hit by thousands of air molecules isn't even going to register on any type of scale, especially in combat. Sure technically it would increase her power, but the power she would gain would be so small that it wouldn't even matter. Getting hit by a giant robot or even getting into a fist fight will definitely register and increase her overall power, as those attacks would have power behind them and Yang would use that power to attack them back.
