Of course, as I said this is what I did too on aircraft without a HUD.
However, if my colleague rotated by coming inside to the PFD earlier than normal I would not have an issue with it as it is exactly what they have trained to do at night / low vis etc.
Trust the instruments is drilled in from a pretty early stage and I’d expect any of the crew i fly with to be able to rotate perfectly well on the PFD.
