How do overlapping actions improve the sense of continuity between poses?

Example Concept: Overlapping action involves staggering the timing of different body parts or elements so that they do not all stop or start moving simultaneously. For example, when a character comes to a halt, their hair, clothing, or limbs may continue to move slightly, creating a more realistic and continuous flow of motion. This technique adds depth and believability to the animation by mimicking the natural delay and follow-through seen in real-world motion.
