It was a general statement, not personaly orientated. Nothing bad. The other thing it means is that I see the SE "Ommmhh" like an improvement (for once!).
Aaaarrhh expresses something that hurts. The "ooommmhhh" is more contained and expresses better an effort - the one he makes to collect his force when he takes the foot stroke. It also *imho* fits totally to a character who's such as he won't allow himself to show any weakness going through.
... You have the "Aaaaarrrhh" after, on the core bridge, when he takes the lighsaber stroke on his shoulder. There, it really hurts!
What he said! I couldnt say it better
