Stalls - Angle of Attack versus Vstall

Not really. You're flying on inertia and prop thrust. You wing will provide
lift with the lift vector horizontal, but when your speed decays to zero,
even though at that point the wing is not providing any lift, it is not
stalled nor has it stalled at any point.

Consider vertical flight. You can have 0 airspeed and not be stalled.
Hope the plane's built for tailslides, though.

So then your not flying on the wing your flying on the prop. This is more
like a rocket.

IMHO, it was a well-intended but poor example. At 0 airspeed, there is 0
pounds of lift.

The reason the example was well-intended is that it's a scenario in which
you could be moving, but in which the airplane is supported by something
other than the wing, and so the wing need not generate lift equal to weight
(as it normally would). In this case, some airspeed below the stalling
speed is fine, and the wing is not stalled. As Mike says, even if the
airspeed falls to 0, the wing never stalls.

But the airspeed is NOT zero. The propeller is causing moving air to be
pushed over the surface of the wings!!

That was meant to be my point.

Maybe not perfectly stated.

It may or may not be. But there's no reason to assume that it is. An
airplane with a pusher propeller, or a jet, or a sailplane, or whatever,
would behave in exactly the same way.
