Whatever they were doing it seems likely that managing the power was not getting the attention it required. In the airliners I have flown you announce your intention by calling go-around then press TOGA and push the thrust levers forward, check the mode annunciation, select GA flap and with positive rate of climb gear up. As far as pitch goes you follow the flight director. Merely slowing the rate of descent is likely to bust the minimum on a sim check, so I would suggest the muscle memory for most airline pilots is not quite as described above. The Emirates 777 Dubai crash is a good example of what happens when for some reason you don’t have go-around power.
