With all due respect to you, Sir, I believe that the author is not mistaken. The term "rain on parade" means spoiling a show. While "reign" is a term for superiority (more like sovereignty) of a ruler, which is usually followed by the word "over", as in: "reign over a country", not "reign on a country". Authors usually edit their articles before they publish them. Mr. Yam is no exception. A minor typo may be possible. But a fatal grammatical error is most unlikely.
