There's a very common misunderstanding among normal users that websites can't really look different for different users. Facebook has corrected that a bit, users now know that features might be rolled out in stages, but they still cling to the misunderstanding that if someone has a feature, they will get it eventually.

And hence this article: Zuckerberg has extra features, therefore everyone will get these extra features. It's pure speculation. A more likely explanation is that he has a special version with a lot more controls that are relevant to him.
