Handstand Wall Leans: Organizing the shoulders for press versus HSPU

Handstand wall leans: a massively important strength and conditioning element for handstands.
It may seem as simple as "lean your shoulders forward and press back" but here are two different perspectives on how to perform the exercise.
Can you spot the differences? They're subtle.

In the first few repetitions I am organizing the shoulders to initiate a handstand pushup or planche. Scapula depressed, allowing the forward lean to happen, allowing the shoulder angle to close, the head going forward.

The final reps are how I would organize my shoulders for a press to handstand. Rather than going with the forward lean, I elevate the shoulders and fight hard to resist the lean. 
Initiate with an elevation in the shoulders, head stays more in(no actual head movement, just the result of the strong shoulder elevation), upper back starts to round a bit.
I know it sounds like a paradox to lean while trying not to, but that is a good simulation of what the shoulders actually need to do in a press handstand. The lower your legs go, the more your body will want to lean forward and collapse, the harder you have to push to maintain the position. This is a way to get a feel for isolating a specific strength element in the press(that's a weakness for many people working on it).
Also notice how when I return to my resting position, I am not fully elevated. The idea is that I have to push much harder when doing a press than I do to stay in a handstand.

As for the wall, I keep my feet pointed and barely touching to the point where they can easily slide. I take this even further and make sure the pressure on my feet is so light that they can come off at any moment. The purpose for the wall is to isolate the strength and activation aspect of the movements while simplifying the balance portion. Any significant lean onto the wall will change the movement pattern and will have less carryover to the freestanding version.
