Palming, POE

[Splute]

After reading the POE regarding "palming", I am having a hard time imagining how the hand can be "facing downward" and be called palming. I understand their point regarding the ball coming to rest at anypoint in the dribble. But I am having a hard time picturing how that can happen with the palm facing downward. I realize you have the potential when the dribbler changes directions and pulls the ball across or perhaps a behind the back move that may cause the ball to rest in the hand extendedly. In these cases the palm is usually on the side of the ball. Can someone state a situation where the palm is facing downward and you would call palming? I do not consider a high dribble to be such a case. Perhaps I am just picking on the wording? thanks
