I'm pleased that someone who actually does the job has said this. I get it completely that with modern traction there is a rule about stopping short and then moving forward the final few feet to couple up. I won't unpack the detail but I was somewhere on the main line recently when the loco returned to its train to couple up. The crew approached the stock as normal, regulated the speed down to less than walking pace and simply rolled onto the train in a continuous movement. A wave of the hand when the loco brake was confirmed as on and a crew member went below to couple up. To my mind it made absolute sense as the important point was that the loco was rolling, not under steam and therefore easier to control on the brake.
