The sloppiness in the AI comes from the human sloppiness on this topic. This seems like a variant of what I've seen called the "fake because", which is the idea that people don't generally analyze whether or not a given reason actually makes sense. For example, the common advertising "You need to buy this beer because it'll get you the girls". It is obvious to conscious examination by pretty much everyone that this is obviously false... the problem is getting it up to that conscious examination in the first place.

I've also noticed several times the deployment of "It's not about the X, {because} it's actually about the Y" where the connection between the X and the Y has no real logic in it upon examination. That can often be translated to "I want to change the topic to Y" without much loss. I think this is one of the primary ways that AI writing can be really exhausting to work through logically and it gets people who are for whatever reason thinking sloppily, including just the sheer exhaustion of the amount of thinking navigating the modern world takes even for someone who nominally understands how to penetrate this sort of sloppy thinking, into so much trouble when they just trust the torrent of words going by. AIs can very easily hallucinate "fake becauses" at a rate no human could possibly keep up with.
