The main (actual) theme of the series is focusing on non 1-to-1 mappings, for any reason (useful or not). It's a thing that fascinates me. The phrase "$x is too high level" is mostly satirical, a phrase I've used for more than just assembly language ($x = [asm, regex, scapy, inflate/deflate, zip, elf, burritos, etc...]).

Taking a look at the blog's main page, it looks like your intuition is pretty much right. There look to be a lot of posts with that catchphrase in the title, but I looks more like a mini-genre than a serial collection.
