Remember, the Slide Hip Turn (10-14-B) is a Slide with a Delayed Turn and, as such, facilitates Motion parallel to the Delivery Line (Plane Line). For emphasis and differentiation from the Standard Action (10-14-A), the photos do not illustrate the Turn component.
Also, take care not to exaggerate this action. The only lateral motion required is enough to Shift the Weight (in both directions).
If a Hitter switches from 10-5-E to 10-5-A or 10-5-B I assume he switches from covering the plane to tracing the plane. If that is the case does the hip slide now go from crossline to down the line?
