pretty much, it couples in with how the game mechanics work. You gain extra AC based on your Dextirity which basically means your reflexes to dodge. But you lose it or the other party gains advantage on them if you can't see the attack or if you are suprised. Which he can't be either of which means he is always on guard to dodge and block.
