I'll bet his spinal surgeon has spent more time studying spinal anatomy than a lay person. My surgeon gave me similar advice decades ago. Some of it is done for liability reasons.
A repaired herniated disk takes time to heal. The surgeon makes an incision into the disk and removes the soft, gel-like material that has herniated the disk. That stuff acts like a shock absorber, and until the incision heals any kind of jostling hurts a lot and delays healing.
