The paragraph before the one you quoted there reads:

> What’s worse is code that agents write looks plausible and impressive while it’s being written and presented to you. It even looks good in pull requests (as both you and the agent are well trained in what a “good” pull request looks like).

Which made me think that they were indeed reading at least some of the code - classic vibe coding doesn't involve pull requests! - but weren't paying attention to the bigger picture / architecture until later on.
