Yeah, it's a very human error type - "go for a line that sounds good on the surface but doesn't actually make sense" is not at all uncommon. Like, humans will definitely go for a metaphor that falls apart mid-sentence even in a live conversation.
Something about the way some AIs are trained to write causes them to go for metaphors aggressively - and they don't always come up with good ones off the cuff. But they don't double back and get rid of the failures.
