But as I'm sure you know there's "windy", then there's "gusty" and there's " ****gusty" jolty stuff..I don't know about Dussledorf but you certainly get teeth rattling gusts at the likes of NRT on a bad day that no doubt have the moving up/down/ left/right bits doing all sort of things on a FBW type that we are blissfully aware of upfront .
As for video evidence without knowing how gusty it was for approach A vs. approach B it is a difficult comparison to make..
He/she may have made it worse but only the FDR will (may?) be able to say if the handling pilot was commanding those rudder movements seen prior to the flare.
