They're using the paddles mostly for the look of the end product, judging from the patting machine processing shown at the beginning of the video. In Elaine Khosrova's book, "Butter: A Rich History", IIRC she claims that there is a difference in consistency when wooden paddle handling and shaping is used exclusively after the churning stage. That's not really what they're doing here; they're just giving the look of it having been done. Understandable though if they're producing so much.
