I didn't catch that on first read, but I see why you'd say that. LLMs are ridiculous in the constant usage "it's not X it's Y" -- It's in almost every response from Opus 4.5. "It's not X it's Y" is ruined for regular writing.

I'm also skeptical of anything that claims to reliably detect AI writing. FWIW, I plugged the comment into Pangram Labs, which claims to be the most reliably and seems to have worked well before. It categorized the comment as 100% human written with medium confidence.
