He is describing the traditional airfoil theory which is correct. It
is the most efficient method as it produces lift with minimal drag.
That's what most people are taught.

There is another mode that is related to the force of the air
impacting on the bottom of the wing at high AOA producing lift as
well.

You make it sound like there are two effects, one that
applies in some cases and one that applies in other cases.
The reality is that both descriptions apply in all cases.
They are alternative descriptions of the same thing, and
both "explain" the effect 100%

Inverted flight is accomplished by the second of the two effects.

No, both descriptions (often referred to as the Bernoulli
and Newton descriptions) are 100% correct and either can be
used.
