IU was correctly used everywhere else in the article except that one place with the mistak, so the LLM didn't hallucinate a correction, it correctly summarized what the bulk of the article actually said.

GPT5.2 does catch it and warns to not trust anything else in the post, saying no competent person would confuse these units.

I wonder if even the simplest LLM would make this particular mistake.
