Does anyone read up on their history? This one goes FULL circle to last night, so pay FULL attention:
When Cena was trying to make his name in the WWE, he had a meeting ON camera with Vince McMahon, at the VERY beginning of the Attitude era. In fact, it jumpstarted the Attitude era. Vince said, and I quote: "You want a shot in this company, I need to see a little attitude. EVERYONE needs an attitude change."
Upon hearing this, Cena turned to Chris Jericho, and knocked him out with a slap. The following week, John Cena was wearing baggy shorts and throwback jerseys.
WWE wants to leave behind the attitude era for good, and this is one of the ways they're going about it.
I think you are thinking of the little Ruthless Aggression era that went on during that time. Anyway the name sucks 'The Throwback' was much better but like everyone else said the name dosen't change the move any.
