Okay, the way it is worded, the first one (the destruction prevention) can be activated at any time, your choice as to when. It just makes it so that when it would be destroyed, it wouldn't leave the field, for one time only. However, the second one (the spell nullifier) must be in response to the spell you wish to nullify.
