Shoving flop wouldn't be an overbet at all. His stack size on flop after he bets: $306. A pot-sized raise would be to $374, which would put him all-in. So it's less than a pot-sized raise.

EDIT: Oops, forgot he had already put $88 in. A pot-sized raise would leave him with $20 left, so shoving is very slightly an overbet, but not enough for it to matter.
