I am expecting a qualified pilot to be slightly better than that ito his IQ.... Did he not even think about things going viral faster than the speed of light? You can argue as much as you wish about the physics around the manoeuvre but Airbus helicopters, even from the olden days was very specific about aerobatic manoeuvres and please don't argue that in the light of "no definition in the RFM of what they consider to be aerobatic" that that is not an aerobatic manoeuvre.
