I doubt that this is a mistake, exactly. It's likely intentional, albeit through unreliable automation. I mean, from Google's perspective, false positives are arguably far less problematic than false negatives. And I'm sure that it happens more than we know. Given that most affected users have no way to get attention.

Edit: OK, so I'm dyslexic. False negatives are arguably more problematic, because they attract more attention.
