I assumed that they would determine from fdr whether or not the plane responded (at all) to contorl surfaces and if it did so in the right direction. Less concerned about whether the response was exactly as predicted (agree with you on that), more with did it cease responding completely or do strange things.
BEA qualification could indicate either case I suppose, or nothing at all.
