There's no indication that this is a replacement for the move wood phase. In fact, it seems to come after the move wood phase, as a player could have played a follower to the second half of a (previously unclaimed) town, then converted the town to a castle. I do not interpret the placement of the knight into the castle as a separate deployment, I just read that as recognition that you physically have to move the meeple to put the castle tile down.
