This is a great basic movement to get a feeling for what is meant by "hollow" and what is meant by arched. Having facility with pelvic rocking is essential to good control of the core and torso for all movement - from squats and deadlifts to push ups and leg lifts. It is also great for loosening up tight lumbar erectors.
