But it does suggest to me there should be a policy that the PIC sit in the LH seat, and that the normal procedure in emergency should be for the PIC to request that control be turned over to him
On the other hand in the case of augmented ops with the captain on break that would mean in any emergency automatically turning over control to the co-pilot sitting in the his/her "non natural seat", the Left one....which might not be the best idea ( the aircraft should be designed to be flown with equal "ease"
from either seat, but a co-pilot's natural habitat is the Right Hand one)
