I wonder if maybe the fact he hadn't used that variety for a year or so was because some of these shots were ones he couldn't play because of his back? Could well be combination of both though because his back hasn't been an issue for a while, but maybe he just needed the confidence to play them again and Amelie helped him with that. After all, a woman's touch can be invaluable!
