Mr. Optimistic:
Other way round - the PF was in the RHS on this occasion. I'm not fully understanding your point either - the aircraft's systems told them that they were approaching stall, and continued to warn them as they went into the stall regime itself. It warned them that they were in Alternate Law 2 without protections. The ADI told them that they were too nose-high, the speed indications (when they came back) indicated they were too slow and the altimeter was unwinding at an alarming rate.
How much more help can you expect the aircraft to give?
