A move of the hips toward the target during the downswing is desirable but, in my opinion, it can't be achieved by trying to move your hips.

To take a Hoganism, turning your left hip back around towards your rear at the same time as beginning to shift weight to the left is the combination of feelings that leads to your hips naturally moving left a small amount. Just moving ones hips left from the top can lead to actually moving ones head and shoulders across too and hence you'd be getting infront of the ball. Cue weak slices, flipping your hands at the ball and shanks.

Try to think of it as the beginning of the turn/unwinding, rather than a slide left.

Then you'll be in danger of looking like my avatar at impact. Coooool!
