It got so bad that it shut off, but corrections actually turned it back on, during a recovery attempt once the speed reset the logic.
It appears that pitch/power relationships that are basic fundamentals to our work were indeed overlooked, but to play devils advocate, one must consider again airbus engineer logic disconnect with the human-computer interface in regards to this accident. This accident chain was started with a faulty pitot/static probe heater.
Once you go beyond certain parameters, even with everything working (or in this case working "again") when things recover it sheds many of the protections. Sort of like its saying "OK, not sure *** just happened but even though all appears normal, you can do what you feel you need to do" sort of thing. So once things get too bad, its your airplane; it won't save you by itself anymore.
