A Caddy mechanic told me that this was true when on any sort of incline. He said, if you noticed that when you set a car in park, then let off the brakes that you'll notice the car roll slightly. It puts the gears in a wrong position and when re-engaging the gears cause slight unnecessary rubbing. Over a long period of time this may lead to a slight stripping of the gear. He claims the parking brake will prevent this shift.
His explanation does make some sense. What are your takes?

Nonsense. Stripped gears means that the gear teeth are knocked off, and the gears no longer engage.
When you put a vehicle in park, it has little to do with the gears. There is a pawl, which is a little arm, that engages and stops the output shaft turning. It is built fairly light, and if you ever put a vehicle in park while it is rolling, you risk breaking the pawl. The gears, meanwhile, are all at rest. Without the clutch packs engaged, they are simply idling, same as neutral.
Using a parking brake is logical, as it is safer. On a steep hill, it also prevents too much load being applied to the parking pawl.
