Those pics are the in flight config where the FCS is reading airflow and engages the LE Flaps and the flapperons to reduce the stall point but are still being used as roll along with the tailerons. Its when its on its final landing where you see a notable reduction in movement from the flapperons. So if you read back they do work together, its on final that most of this is loaded to the tailerons. I'm trying to find one of the footages that show this, where like I said you had a strong taileron movement with what appeared to be none from the flapperons. The ratio is handled by the FCS either way or at least that's what my inlaws advised.
