I used to be like that guy. Worked in a call center for half a year to make some money and always tried to be "fast and take as many calls as possible". Made more errors and problems than people that made half as many calls. Not always the best idea to be as fast as you can in your job.
Judging by that one tray toss I believe their job is also to do some sort of quality checking or seeing that the packaging is not damaged. I'm sure he is experienced in spotting faults, but if that is his regular work tempo and if he works the 8 hour a day, he is doomed to let slightly faulty ones through more than the average speed worker. He is fast yes. But is he good at his job? Questionable and debatable.
