Actually I believe this particular example is basic and pretty understandable C. I was talking about the more broad idea of knowingly writing clever code to raise the entry barrier for new devs. Or just writing clever code for whatever the reason. It's almost guaranteed to backfire, to new devs who will have to maintain it or to yourself, when you will have to read it in a less smart moment.
