No, i was saying that during automatic approaches the rudder servo (not the yaw damper and not the trim) works parallel. That is of course only valid for NGs that have an CAT IIIb capable autoflight system which includes automatic rollout and single engine CAT IIIa automatic approaches and go-around. For that to work it has a rudder servo and a rudder autopilot channel. Many if not most companies don't want the extra training, certifying and maintenance cost of that system and therefore never order it although it is available for at least 5 years.
And that kind of operation seems to be somewhat similar to 411s description of how his beloved L1011 works.
