this "error" maybe defined as a consequence in which that crew made a decision to increase risk unnecessarily with extreme manoeuvres on approach.
This error had that day no outcome consequence of the completion of the flight but learned before that crew errors were implicated in quite numbers of accidents especially in approaches and landings phases.
Trusting the crew was well aware of the conduct of such manoeuvre, CX management had differrent point of view and probably took action in the light of operational decision error for the risk taken.
