My understanding is that it was too disconcerting and distracting for the pilots to feel the rudder pedals moving under control of the (parallel) yaw damper at take off and landing, so it was only switched on for cruise once the pilots had their feet up.
You understanding is rather inadequate, richatom.
The parallel yaw damper was switched off for takeoff and landing due to excessive rudder pedal forces necessary with it ON and an engine inoperative...an outboard engine especially.
ON at 1000 feet agl in the climb, OFF by 1000 feet agl, during the approach.
