And bad comment :-/
Nothing personal, this is intended as constructive criticism.
You completely ignore the main point of the article, and come quibbling about an unrelated detail.
This kind of comment often ends up at the top of the comment thread and obscures the comments that discuss the subject matter.
Your point is rather obvious, and I suppose that you end up being upvoted by folks not knowledgeable enough to discuss TFA, but feel validated by the fact that they also spotted the error.
