According to Chris Caldwell,
http://primes.utm.edu/notes/by_year.html#table2

the last time the largest prime was not Mersenne was 1989.

So I guess the guy just made a mistake.

Normally I would just blow off an error like that, but the guy writes articles for the MAA, so I'd expect him to be up on his stuff. I was wondering if there's some reason why he would write that.

Sorry, what I was trying to say is that there is nothing else in the article to give support to such statement.
