Learmount's summary is substantively correct in most senses, but what he does not acknowledge is that during the initial events of the sequence, the PNF tries to draw attention several times to the PF that he thinks the aircraft is being mishandled. Unfortunately, for whatever reason, the PNF elects to defer the decision to begin corrective action until the Captain has been summoned to the flight deck.
