You're absolutely right. On a vehicle with both rear drum brakes for the parking brake and rear disc brakes for the service brakes, the drum brake shoes are indeed only actuated for the parking brake function. As such, the drum brake shoes should last a very long time and not wear out from friction like the disc brake pads, since they are not used for normal braking events.
