Appears he did. Cancelled a non-ignorable, non-cancellable warning by returning to well above normal pitch angles for phase of flight and stuck with it. Which isn't to say it's not possible to exceed critical AOA while staring straight at the ground. Entering stall/spin regimes almost exclusively the domain of GA or military training, an already identified but as yet not addressed aspect of the problem.
