By michalpolko:

If we have 1 aura in holder and it passes the mechanic mask check, then it will not be removed here, because it is last aura on holder, neither will it be removed as whole spell, because removedSingleAura is already true in this place of code. So this would give wrong results.
Correct me if I'm wrong.
