Not both at the same time though, which is what they mean. Or rather, if you're hitting Combo I, Combo II doesn't also change along with it. If I'm using Combo I and then start using Combo II it makes me start at the beginning of II instead of its Combo I equivalent (at least that's how it works for Monk).

Example: Combo I for Monk is Bootshine > True Strike > Snap Punch and Combo II is Dragon Kick > Twin Snakes > Demolish.

If I use Combo I up to True Strike and then press Combo II, I'll perform Dragon Kick instead of Twin Snakes. This works OK in PvP where abilities have drastically different effects than normal, but in a PvE environment where you might work on a priority system and not a set 1-2-3 rotation, having skills forced into a set order would cause a lot of issues.
