SECTION 44 VERTICALITYVerticality applies to a legal position. The basic components of the principle of verticality are:
ART. 1 . . . Legal guarding position must be obtained initially and movement thereafter must be legal.
ART. 2 . . . From this position, the defender may rise or jump vertically and occupy the space within his/her vertical plane.
ART. 3 . . . The hands and arms of the defender may be raised within his/her vertical plane while on the floor or in the air.
ART. 4 . . . The defender should not be penalized for leaving the floor vertically or having his/her hands and arms extended within his/her vertical plane.


As I read this, the ability the legally jump (verticality) is available only when in a legal guarding position. If the defender loses legal guarding position, they lose the freedom of movement (lateral or vertical) at the point of contact. They own the space they are in, always. But they can not extend their space in any direction.
