How do you square this with the cable carrying an AC signal?

Arrows on all other kinds of cables -- XLR, speaker, power, and data -- are utterly meaningless from an electrical standpoint, since audio signals (and wall voltage) are alternating current and interact with conductors the same way in either direction.
This explanation, while common, ignores the fact that we are transferring energy in one direction. The oversimplified view that we have electrons flowing in one direction and then they all flow back the other direction so it all balances out works for some very simple electronic models but falls apart when trying to use it to explain transmission lines (cables).
I’m not arguing that a perfectly symmetrical cable is directional, only that the explanation used is not applicable to what is really happening.
