Not saying they did it right John, and the procedure clearly dates the video from before 2010 which is when I was Standardised and then passed on the training which included landing on the bum line, no crewman in the door and putting the brakes on.
Up until 2010, there was little DL training except in the sim on the OCU as we had operated on the basis that RNSAR had - ie that a SAROP was a SAROP and could be treated as any other 'situation'. The grey funnel drivers realised, with more embarked ops happening, that everyone landing on a deck needed to be formally qualified - step forward (or was I pushed?) crab@...... but it's all water under the bridge now.......(see what I did there?)
