I really hate the guy but if you've never had a near-death experience you wouldn't understand that your logic is a bit weird in the moment. it takes more than a couple of moments for your brain to catch up with reality. his shoes are special thick lift shoes to make him seem way taller because he's extremely vain. if he fell out of his awkward tall shoes when he ducked, he probably would have been preoccupied in the moment with not appearing short and weak (his true form) until the reality caught up to him. I don't doubt at all that some sycophantic pr stooge was yelling into his earpiece to "look triumphant, look triumphant!!" when he was getting back up though.
