Errr, what does consciously deciding when to pronate and supinate while hitting have to do with the question? Did isilra ever say he did that while swinging? The point is that some players actually do this and some don't, and the swing types end up being a bit different as a result.
I'm not well-versed in these matters, but it doesn't seem outside the realm of possibility that different swing types would benefit more or less from different racquet specs. So I'm not sure why you're so scandalized by the question...
