For what I heard in creating models, often head (or face) is separated from the rest of the body, because of the complicated facial expression you make with "bones" - it would be messy, if the head and the body are connected. Maybe it's for that, also because I've noticed this with other videogame characters - that's why you find this "glitch" when you stop the time.

It's... normal, in other words.
