Okay, you have a point, but with good prediction you could Cross Chop when they roost or something. I am not saying you are wrong, I am just saying that regardless of Zapdos having roost, CAP6 can potentially stall out non-offensive versions with Recover.
If you Cross Chop while Zapdos roosts he finishes you off next turn as you didn't heal, so it's still not possible but i get what you mean.
