Exactly where does this cyclist expect a UPS truck to park? (and I'm assuming the UPS guy was delivering packages, not out to lunch) Those trucks are huge; they're going to be blocking something no matter where they park. If I was coming up on a UPS truck parked to the left of a bike lane, I could see many circumstances where I would still pass the truck on the left. If I stayed in the bike lane I would be shooting "out of nowhere" on the other side. Nobody is entitled to his own curling sweeper.
