If 2 Aura Breakers are on the field with a Pokemon with Dark Aura/Fairy Aura, would they cancel each other?

Question

What would happen if there are 2 Zygardes in a battle with a Xerneas/Yveltal? Would Aura abilities be reversed twice, meaning they would still be active?

Answer 1

No, they do not cancel each other out.

This would only be possible in double battles, but it's just not possible at all.
