If the feet are level and the instep high your knee will be foreward of your body. The hip movement you can see is the knee slightly lapping the standing knee then pushing off.

Don,
you mean it was not really a hip twisting, rather only light 'knee twisting'?

At least not intended as hip twisting. Yeah?
I've watched the movement frame by frame and can say I nearly agree with you...
It's all there for the looking. If the music is too fast this is the first action to suffer.

I meant any explicit hip twisting in this chasse considered as a mistake for competition dancing as far as I know.
