Reviewing is a very different mindset than writing it yourself. You don't have all the context you would have built up had you done it, and it's much much more difficult to think through all cases. So I'm thinking: The individual changes all looked good in isolation, and they started borderline rubber-stamping the changes without stepping back to think about the larger context.

Looking at the individual changes in isolation, it's harder to see it doesn't match other conventions, duplicates code, removes or disables paths without cleaning up, etc. I'll bet there's also some crazy spaghetti code in there, from helping a co-worker clean up their Ai-generated code that they didn't understand.
