What the shop told you is nonsense, and quite often a way some shops pad their bills; you only need to cycle the ABS/PSM system if the brake system has been either drained, opened up for service (e.g.: replacement of the system pump and associated valves), or has gotten significant amounts of air entrained in the system.

We only need to cycle maybe one out of 50 to 100 cars, usually because we had to open the system up for repairs, or the car came in on a flatbed with the system already open. Otherwise, the Motive pressure bleed system is used in the normal bleed/flush sequence............. You're fine.
