David, it's also the effect of the impact in addition to being a third attack. It can be a responded to by something that can only respond to an attack (though, since the attack can't be nulled, it'll have to be something like Black Dragon Shield). The impact itself can be nulled and that'll prevent the attack, too.

But overall, the difference is in the wording. It's "attack with it" vs. "can attack during final phase". The first is that the attack is the impact, whereas the second is an effect the monster gets from the impact.
