The release to the spread eagle position is not legal because it is initiated from below shoulders. That makes it a toss. So, it would have to be cradled or braced. They can pump and go through a prep and then do it. That would make it a legal vertical release to a vertical. We consider the “X” position to still be vertical. If they sit into it and make it a straddle sit type of position, that would not be legal.
