I'm pretty sure it was a different Mudra, but I also believe it's going to be one of those things that a player will never get and just be exclusive to the NIN storyline, but who knows, with the Level cap increasing to 60 in Heavensward we may well see an extra Mudra, would be an incredible pain in the ass to memorize 14-15 different Mudra combos though so I can't see it happening :P
