Once more... IF the decision has been made - regardless of how/when/why - and the PM IS going to say something, why not something recognizable and valuable? "PULL UP!" is both, where "Pitch" is nebulous at best, especially if the PF is disoriented.
AFTER the nose-low attitude is corrected and they are flying away from the ground, they can discuss failed PFDs, failed PIT comparators, and sensory illusions ad nauseum. When time is critical, though, a clear, recognizable command with one logical response is best.
