Picture your profile, showing the right side of your face. Imagine that your upper and law jaws could be rotated in a circular fashion when viewed from the viewpoint. Counterclockwise rotation would involve the mandible being brought forward, the maxilla being brought backward, the front of the maxilla and mandible being brought upward and the back of the maxilla and mandible bring brought downward. That describes a counterclockwise movement.
If one's objective is to get greater maxillomandibular projection, counterclockwise movement can be made at the same time both jaws are brought forward. Doing both of these would create relatively greater mandibular increase in projection then increase in maxillary projection.
As far as your decision making process goes, I recommend that you assess your own aesthetic objective, and then determines, if indeed you wish any change to be made, whether or not it will work, what are side effects, and perform a cost benefit assessment to determine whether or not to proceed.
