Great question, and I have only a poor answer, Firefox spell check.  You would think that I should know better ans shouldn't have assumed spelling errors on that page, being a protected template and all, but they did look "funny" to me (being US-English native) and I made a bad fix.  My primary reason for editing that entry was because it seemed that we were being to sensationalistic, and I was trying to make it more straight-fact, and didn't see the forest for the trees.  I support whichever regional English variant is the most topic appropriate or has already been extensively used in the page being updated normally.  Apologies, —  Talk
