Sorry, if it somehow sounded that my example is somehow more than what was mentioned in the article. Absolutely not. I think that my example also very well demonstrates that lines of code (even that isn't really "code") isn't not a good way of measuring productivity etc. My example could be considered as an example of how a code review didn't "do it's job" for what might have been a newbies mistake. But I also think that code reviewers cannot be blamed for every bad piece of code that gets through (context matters).

“Not much of an achievement, but” here refers to the commenter’s action, not the one in the article
