At some point in the article's history, the idea expressed by this passage was followed by some discussion of airflow on both sides of the wing and the point made that some explanations only involve air being deflected by the bottom of the wing. (sometimes called "bullet theroy" or "skipping stone theory").  This was accompanied by a graph showing the pressure distribution along the top and bottom of a wing where the pressure difference along the top was substantially larger than along the bottom.  At some point this was excised, whether by accident or not.

Which is to say that your interpretation of the intent is correct.  I can see where what is actually written may be interpreted differently than what was meant.  A suggestion for how to reword would be welcome.  I'll take a look at earlier versions and see if we edited something out that shouldn't have been.  Personally, I don't read the passage as a statement of cause and effect but I can see how someone might interpret it that way.
