Frankly, I can see no benefit from teaching that position, and without seeing it, I have a difficult time seeing it as being a natural stance.

To squat and lean back, most likely requires a base wider than shoulder width, which can get you called for an illegal screen if the defender gets caught up on the extended leg when going around.

The extended arms means first contact is with the arms of the screener, which can also get you called.

Seems to me to be a very bad technique even if it is perfectly done.

Remember screens are supposed to be a passive act, every thing about that stance is aggressive.
