This doesn't answer the original question but it does provide some insight to the overall topic.
I found this in D. P. Davies, "HANDLING THE BIG JETS" page 261 in the paragraph under stability...
"There is no significant dutch roll in any flight regime and while yaw dampers are fitted they are not required for despatch".
For an multi-autopilot (engine out go-around), yaw is initially controlled by the autopilots. Manual rudder input must be applied when selecting another roll mode, pitch mode, or when altitude capature occurs above 400 feet AGL because the autopilot reverts back to single-autopilot operation.
Hope this helps.
