Yes and no, it depends on the cast and foot placement. In a perfect world Our feet should always be facing the direction of the forward cast, but if you ever fished the Thomson river you know better. So some times there is body rotation to get to the desired angle. As I think about it more most casts will have some rotation, do switch cast now do switch cast and add upper body rotation and you have a single spey. The "in the box" is more about hands and elbows. The single, double, snap t / circle all have upper body rotation to get to the desired casting angle, hope this helps.
