They must be comparing a wired track ball mouse to wireless mice.
Having used trackball mice quite a lot before optical mice became common place, I can see a good wired trackball mouse being more responsive than an optical or even wireless laser mouse, but you would have to buy a truly craptastic wired laser mouse to find a trackball mouse better. The only way I could see it even being a possibility is if your desktop is made of glossy plastic or something else that could confuse the laser.
Something about all the “evil boss” movies of the 80s and 90s really stuck with that generation. It’s like they picked out the lowest of lows from the movie and said “you know what as long as I’m better than that I’m a good boss and people should be happy to work for me”.
