I realized the same while reading it, but my impression is that the output has been well edited. The typical Claude density has been pulled out into something more human readable, but with many of the Claud-isms still intact.

Personally I find this a productive way to produce documents. Claude makes the first pass and I edit line by line. It’s a good understanding check. If I can’t reword something into my own voice it means I don’t understand it. Then have Claude loop again to fact check the rewrites and repeat until clear (or I disagree with Claude on all it’s remaining points).

That’s the same edit loop I used without LLMs, but I get speed in drafting up front (and fact/number pulling) and the check passes make the edits better.
