They're not referring to the m-dash that LLMs are known for, but hyphenation in the middle of a word to split the word over two lines.

The article shows it in the example screenshots, but does not explicitly mention it or how it interacts with the different options discussed

TFA also isn't talking about code comments, but considering the comment chain I'd like to point out that the only times I've seen hyphenated words there is when I'm pretty sure they were LLM generated... So... Unless the position for the hyphenation changes depending on the resolution (or page layout like with latex), I'd personally still guess an LLM was involved, honestly.
