I mean yeah, it does have that problem, but even if it's not entirely accurate it's good enough to illustrate an otherwise abstract concept that's not exactly easy to understand for someone who's just getting started with programming and may not really be interested in it, rather looking to be an artist or game designer. Also humor really helps when it comes to learning. It does way more good than bad in my experience so far.
Yes, that's true. It's also good enough to make an abstract concept more approachable while getting a kick out of it too. Honestly this is more of a "well akcshually" thing that someone who already knows how this works would point out (nobody has so far) than something that misleads students who don't get it. It works.
