Unfortunately, the safety logic and emergency handling protocols that have evolved following many instances of the 'flashing white glove' shutting down the wrong engine or selecting the wrong system off, mean that sometimes we will see malfunctions like this where the old school are shouting 'Do the drills from memory and shut down the engine because you don't know what else is wrong' and others are following company policy and the RFM because then you can't be hanged in court.
This guy was possibly caught between a rock and a hard place and just followed what he had been trained to do.
