When saving a body pose to the library, you are given the option of including Morph Channels or Body Transformations. The second one will include any movement or rotation of the entire body. Otherwise the figure will be posed in the zero position, facing in whatever direction you have set the hips to face.

The Morph Channels option is for when you want to inject a saved set of morph dial settings (such as Amazon or Tummy Out or Breast Size) into a figure. Normally when saving a pose to position any V4 figure, you wouldn't include these because it will reshape the figure.
