I wouldn't knock the SSL's at all, however over-simplification leads to holes in the logic which causes problems when someone subsequently tries to work out what is happening, as in this case.
John Farley has a very good explanation of how he explains lift to novices in the latest issue of "Flyer".
He says "Personally I hate oversimplified or misleading explanations that do not bear close examination. Plus where I come from there is no such thing as a weak student - only an incompetent teacher (at least for something as basic as aerodynamic lift)."
I tend to agree with him.
