If you have any ability that lets you ignore the movement penalty of Sneak then none of the personality movement visuals work other than regular walking. Not even regular sneaking animation, which is very annoying for a thief build.
Also, the running animation does not work at all on any character. When you run it reverts to the normal animation. And when you run in Sneak the animation does not work at all either, it reverts to the normal sneak-run animation.
Basically, most of the movement animations of this personality do not work. Those animations are present when you preview but not in use after you purchase.
