When you saved the pose, you probably chose to save the figure's body transformation as part of the pose.  That includes the figure's location.  This option is right after you name the new pose.  Poser asks if you want to save the morphs as well as the pose, and it asks if you want to save the body transformation.

You need to save your poses without checking the body transformation option.  Then the figure will move into its new pose, but will not move its location.
