Except that's the point of the article – PCD/napping/etc works because the default mode network of your brain is more active when you're at rest than when it's focusing on something, and that it seems to be doing some "housekeeping" in your brain so to speak. I don't think it's much like a minima, because I can go home, run some errands, cook dinner, surf the internet, read, etc, but when I'd come back the next morning I'd be just as stuck as the day before. For me it wasn't until I explicitly tried to do nothing (i.e. wander, as opposed to distracting yourself with other tasks) that I made progress. (of course this is just anecdotal experience – not trying to frame this as The Way but found it interesting that there's some research about it)
