The rudder inputs may not be pilot induced, I've seen a video on you tube of a go round I did in Storm Doris and the rudder was going left and right all down the approach after AP disconnect but I didn't move the rudder pedals at all, it was the yaw damper working overtime in conjunction with aileron input.
PS you can tell it was a Windshear go round because the gear and flap stayed where they were.
