Not much difference from when the autothrottle is engaged on the 737 either, most probably a common part across most if not all types then (broken and fixing and all that eh?). Very useful to be able to do IMO, autothrottle can get a bit eager to stand the thrust levers up again when decelerating and running flap out, just lean on them to show 'em who's boss
(I'd rather they err on safe side than get lazy though!)
