We'll have to disagree on this.
As you say, there is very little sideslip in the early stages, but plenty of roll,which must say something about the roll/sidelip ratio
The yaw damper trace shows there was oscillatory behaviour in the yaw rate at a period that roughly equates to what one might expect for the dutch roll of an aircraft of this size in cruise, which contradicts your view that the motion was nonoscillatory
the spiral mode is never oscillatory so I don't see how you can claim that it dominated the initial rolling cyclic motion.
But anyway, all I was trying to say was that dutch roll characteristics get wprse as AOA increases, and your later remarks seem to confirm that.
