It's because there's clearly a near-1:1 ratio of input to output. I also noticed some LLMisms, and I suspect the author may have ran the text (perhaps in the form of a large number of bullet points) through an LLM. But because he's using the LLM to clean instead of multiply, it's still worth reading.

Probably similar to what I do with my papers and resumes, I write them myself then throw them through LLMs for suggestions and corrections, manually reviewing the output.
