I think - and I'm no expert, so don't quote me on this - that as long as each speaker is wired the same, you'll be fine. If they're different then they'll be out of phase. I don't think there's any danger of damage.
I always thought this too but I accidentally wired them differently on my newish Denon recently and it went into Speaker Protection Mode. Could just be a cool gimmick of course.
"Speaker protection mode" sounds a bit modern. All I know is that if you have two guitar amps running at once, and they're not in phase, there's a quick fix where you swap the speaker terminals over on just one of them.
