Having met the captain involved on two occasions, and sat on his flight decks for several hours including landings (back when that was permitted), I can imagine all options would have been seriously considered and prepared. Until he got it onto the ground he would have had no idea of the cause or the scope of the damage. Preparing the passengers for all possibilities while he had the opportunity would be exactly what I would expect of a professional captain.
Given his training and experience in putting RAN A4s down onto a floating runway, he would be very aware of the danger and issues involved in flying a damaged aircraft to a safe ending. From his description of flying the A4, it was probably much like controlling an aerodynamically challenged house brick, so a damaged 744 may have been a challenge that brought him back to his flying roots. But of course a 744 does not include an ejection seat for each person on board.
