I just felt like posting, so here's a quick note. Someone else might tear it apart, but at least we get this started.

I understand that the role of the right shoulder in the golf is that it stays back and on the plane.

"Back and on plane" does not sound bad.

The actual role of the right shoulder depends on whether you are hitting or swinging. Swingers use it as a flywheel - spinning down on plane - once the hips have lead the way. Hitters uses the right shoulder as a base for "the hit", so it'll stay more "back".

Now if the right shoulder moves forward or out towards the target line,how does that affect your golf shot?

Shoulders moving out sounds like level shoulders. That would cause roundhousing, i.e. going the wrong way. The eyes will tell the Computer: "we'd better do some out-to-in if we want to hit the ball at all".

The shoulders are leading the clubhead to a location high above the ball. The Computer does not want that. So it'll tell the hands to fix it. The reaction is flipping the hands in order to make the clubhead hit the ball.

That will in turn default to a pull, duckhook or hook. The hook tendency is often combatted by an open face and/or chicken-winging, most likely causing a slice.

Either way the result depends heavily on hand manipulation.

Does not rotating your hips automatically cause the right shoulder to jut out?

No. Hips and shoulders do not move as a unit.

In general I feel getting the shoulders on the right track will immediately take the game to the next level.

Not saying it is easy.
