Archetypes are chosen when you trade something out. As soon as you do the ability swap, you become the new archetype.
Quinggong Monk does give you some leeway on when you join, unlike most archetypes where the jumping on point is set in stone. If you choose not to trade your Slow Fall ability out at 4th, which is the first available possible Qinggong ability swap, you are still just Ye Olde Monk.
