Tilting Your Torso Away Before Backswing

[DrMetal]

So I was trying to correct my slice, saw this video:

That suggested tilting your torso to the right (rear, towards the ground), as in the screenshot below: 

 

The tilt worked! Now I have a mean hook. I noticed that if I exaggerate the drop of my rear shoulder (before I initiate my back swing), the result is a bad hook.  If I bring the shoulder up (in other words just a slight tilt down), I get a straight shot.  So in essence, can I modify this tilt (can I adjust the level of my rear shoulder) to guide the direction of my ball?!  

Why does this work by the way (in straightening out your shot)?  Is it b/c dropping the rear shoulder before the back swing gives you a sort of 'head start' in initiating your shoulder rotation?  (I definitely feel like my shoulders are rotating more in the backswing, and hence in the downswing as well).

This thread is about driver but talks about the importance of axis tilt. I haven’t looked at your video but this will give you the reasons why as opposed to having a gimmicky thought in your head.

Because if you drop your head away from the target and tilt away from the target, you're more likely to swing out at the ball.

Makes sense.   Would you advising using that (your tilt angle) as a means of straightening out your club path, and hence your ball flight?
