I'm surprised the guy writing this is a US national master, he should know better.
1) There is a huge difference in winning a round robin tournament vs. a head to head match in chess. The psychology is completely different. Anand has played in many matches, so he knows what to expect. Carlsen not so much. Carsen is also playing in Anand's native India.
2) The author puts too much stock in chess ratings as the absolute measure in chess ability. Elo has its own set of issues (e.g. rating inflation over time).
3) The author also fails to point out why Magnus rating is so much greater than Anand's. Anand simply has less incentive to play in open tournaments knowing he is going have to defend his title in a years time for a big cash payout. Throughout the course of studying he finds novelties (moves that have not been played/analyzed before, but he thinks are solid moves) and he does not want to tip his hand (preferring to have his opponent try and figure out the continuation over the board instead of with the help of a computer.) The result? He plays in just enough tournaments to stay sharp and in those tournaments he plays safe chess.

4) There is already a Grand Slam system in chess.
