And of course I'm aware of that, but it's related.

I'm only reading this on the main page:
And the descriptions on PMF are not exactly helping either.

Not a link, but I can try to explain.
It does not measure dynamics over time, or the difference in volume level between sections. It's primarily a reading of the average difference between the highest and lowest levels at a given point. Any natural sound has several "layers" to it that are at different volumes, so a collection of natural sounds will have a wide range in dB in any given instant. Pretty much any recording has some compression applied, though, to make more of these sounds audible. If too much compression is applied, the sensation of all of the sound being present all at once is unnatural, but it can seem to pop out of the speaker, especially on cheap equipment. A collection of the highest points of a track is collated and the average is taken, giving a general idea of how much "breathing room" the track has in general.
