Because the hinge, shaped like a carabiner; has a strong axis and a weak axis; and in calcualtaing lean in 2 directions, you are really looking at how the lean addresses the individual strengths of the 2 seperate axises in the hinge.
In a carabiner we load to pull across the major axis to leverage least, in a hinge we set the target across the minor axis of the hinge, for we want that pull to override the hinge and bend it; an opposite need, so opposite strategy, but still same mechanichs.
