Forum:Arcane Barrier ruling

I've come across an alternative to the ruling on "Arcane Barrier" on another site and was wondering which one was correct.

Here on wiki it states;

"Arcane Barrier" does not gain Spell Counter(s) when Face-down Spellcaster-Type monsters are destroyed, because a Face-down monster is destroyed before you can confirm its Type.[1]

And yet during the damage step the monster is flipped face-up before it is destroyed. So i'm wondering whether or not "Arcane Barrier" would still get it's counter or not due to the fact that when it is destroyed, it is no longer face down.

Cheers.
