Chris, as much as i respect dans view i think that the re raise works BECAUSE of the stack sizes.
He can easily fold to your raise knowing that he is now committted to another $200 or so with only 27 in now (ie you arent folding).
HIs play looks strong (as it is a cold 4 bet) - but therefore it is an easy play with minimal exposure compared to his stack. Below is a hand i played a similar way (cross posted from the rush poker thread). I make this play alot - i have raised UTG in teh rush poker format, therefore my 4 bet looks super strong - but i can still fold if he 5 bets. FWIW i havent seen a light 5 bet in this format yet.
