"This is not just about good thing, it's about another good thing." That "it's not just A, it's also B", or "it's more than A, it's B too" show up most any time you ask it for "persuasive" copy, like marketing, sales, or a rewrite of anything to make the reader a buyer.
It's disproportionately common in GPT-4 copywriting or copy-editing, relative to human copy.
Similar to seeing the word "Overall, ..." for a concluding paragraph, another tell.
My personal favorite is, "It's important to note..." I asked it to stop using that phrase or variations and that lasted one prompt. I'm tempted to put the phrase on a T-shirt.
Someone might be getting editorial help from GPT-4.
// Or a human might be getting fine-tuned interacting with LLMs, which I've noticed happening to me.
