I see what you mean. Yes, that 10 deg rudder seem to fix a right deviation back to centre-line. It's almost 2 seconds and markedly larger than normally expected.
The plot is missing LOC deviation to see the lateral offset. Following your line of thinking, another would be the brake pressure for wheels 3&4 and their temperature.
To my experience, without a small aileron input the plane has a tendency to go downwind. And theirs (during the roll) didn't despite the left rudder input.
