Yes the AQ can and should be two sets of cables, so no concern about awg.
I believe he is recommending using two sets of speaker cable for speakers that have 4 binding posts. You can definitely connect multiple speaker wires to the amp side. Either you double-stack two spades or you use one spade and one banana. On the speaker side, one "normal" speaker cable is attached to the top binding posts and one for the bottom. You are still buying two sets of speaker cable.
