You do raise a fair point. But in this case, does Ulquiorra mean destruction, as in, the complete destruction of Las Noches? Las Noches is a big place, after all. The Gran Rey Cero used by Grimmjow, for example, wouldn't be enough to cause that kind of damage. But on a smaller scale? Sure, it'd do a fair bit. I think that's what the rule here is driving at. Yammy, for instance? He's strong enough to smash through the walls of Las Noches. Ulquiorra? Tore Ichigo through many a pillar before Hollow Ichigo took control. I think it's more about potential damage.

But I do agree. Yammy being the 0 Espada is a big plot hole.
