They didn't claim it's normal. They diagnose it with first video incorrectly. Not many car brands even diagnose you via submitted video record. I'm a tesla owner. With regen brakes the motor do the breaking 99% of the time. So due to that tesla quite often doing a noise that makes people think something wrong with the car, simply because this breaks are not heavily used. It's probably among top 5 false complains to service center , when car is totally fine but people are worried. So SC person did realize its not a false positive signal. As simple as that.
