benbreen just missed the "-3" at the end, or maybe even removed it intentionally thinking it was a link to the third page of the article. It is interesting that the date is ignored in the URL. It looks like the part after the date is actually an identifier for the article made up of the title + "-1", "-2" etc when needed. The Sacks article is the third with the title "Altered States."
