Good question.
Push-presses require very little force application from the shoulder complex. If taught properly, the push-press focus is geared toward hip extension. The axial loading and shoulder extension are just a byproduct of the mechanics of the lift.
A standing shoulder press will also offer axial loading and shoulder extension if done properly but, the total amount of force absorbed and applied by the shoulder complex is far greater than the push press.
