Which Colbert was that again?

I enjoyed Charles McGrath's profile of Stephen Colbert in the New York Times magazine. McGrath's framework is that there used to be two Colberts, the man himself and the blowhard-pundit character. Now there's a third: a real live political actor, based on the TV character but moving beyond straightforward fiction and parody into some nebulous new territory.

I think that's all about right. But I don't know why McGrath writes off Colbert's 2010 congressional testimony as part of the old paradigm:

In 2008, the old Colbert briefly ran for president,
entering the Democratic primary in his native state of South Carolina.
(He hadn’t really switched parties, but the filing fee for the
Republican primary was too expensive.) In 2010, invited by
Representative Zoe Lofgren, he testified before Congress
about the problem of illegal-immigrant farmworkers and remarked that
“the obvious answer is for all of us to stop eating fruits and
vegetables."
