You might still have got it on a Grosvenor (if GIB was familiar with the concept) if you had not exited with the HJ. If you started with 9xxxx and GIB played this way it might go down in a cold contract so actually a good player might play for you to have done this and still get the endgame wrong.
EDIT: Sorry this analysis is only relevant if North had K9 hearts on the actual hand
