No, I understand that part. That's what I said in my original post.

My point is that it's the pulling of air downward and the resulting low pressure at the top that creates lift, not the speed difference itself.

I'm emailing the NASA guy listed at the bottom, because I think section 3 of that article is unclear. In section 1 he specifically states that it's the turning of flow that creates lift, then he says you can explain lift with the air speed difference. How can it be both exclusively? You should have to add those two together.
