That just seems to be how McQuarrie poses his drawings. I think he must have been using clothing catalogues as reference because his poses are either "heroic" or they look like that He-Man, where if he was posing for a 70s swimwear catalogue and carrying a parasol and a towel it wouldn't look out of place. 70s fashion catalogues have some really wild poses that look like someone trying to act casual while tensing their entire body.
