I can vouch for the fact that good ole Captain Van.d.B advised using aggressive rudder inputs having seen the video of the AA symposium when it was first mooted as part of company training.
The difference is that these inputs were only advised during LOSS OF CONTROL resulting in an unusual attitude ie up to actually inverted.
The relatively minor controllability problems caused by wake turbulence as shown on the Beeb should not have necessitated these inputs, the A300 is not a 172.
The CRM aspects of being spring loaded or predisposed towards a particular scenario were barely covered.
