Positioning means "Taking a position, attitude or posture in the face of a public matter." or "Place or place a thing in the proper position." Therefore, REposicion means changing and re-taking a position, either of an attitude/posture (person) or of an object. You can reposition an individual in a competition (such as in a car race, that a competitor can be passed by another car or move on to the front car), in a ranking, or perhaps he is a political figure who changed position.
