A real basic way of putting it is the wing quits flying as the center of lift moves behind it while the tail continues to fly.

So basic its untrue!
Not only untrue...it's total rubbish.

In the 'old days' of the NACA, much work was done with various wing designs/planforms, and although mach tuck was a bit of a mystery at that time, it was certainly recognised that all of these wings had a 'forward/downward turning moment' and the faster the wing was accelerated, the greater the effect became.
In fact, some piston transports had a 'mach number limitation', and...in the case of the DC-7, that limitation is M.585
