Yeah, at least from my quick glance it looked like the special came out in 2011, which would put it around there. There's fuzziness on either side -- on one hand there was presumably some editing time, on the other he seems to have kept it private, presumably whoever told TMZ found out a little bit after he did, and their memory might not have been perfect. It is just in the ballpark.
Interesting in context -- wonder if he knew at the time, it would be right at the limit of the time-window described in the article I guess.
