Well if he knows he can hide in his shell I'm pretty sure he'd figure out the air blast thing. Specially since Ben would have to actually scan a Geochelone Aerio since it's not normally present in the Omnitrix. So he somehow didn't see one in action and missed his other powers. Just seems unlikely.
