I think he means CP-ing with characters, that you're allowed to switch characters between games. Rather than matches, as it was before. Pretty much, here's how it works. Player 1 picks Ness. Player 2 picks Lucas. Player 2 loses, and is allowed to change characters, but Player 1 has to be Ness until he loses. It's rather hard to do with stages though, since it's kind of up to luck :S...
