When raising up the window all the way into the hard stops, do you hear one click, or two? Look at those before/after clips and notice how before it goes cli-click because it hits the rear stop first? It's really subtle but with the tape, you can see the window rotate clockwise as the front keeps going up.
Either way, the mechanic was a slacker throwing parts at it when it only needed adjustment. He may even have been careful about maintaining the same adjustment after replacing the regulator.
