From Gamespot, Sidekicking system:
Another question shifted the discussion to how the game's AI accommodates mixed-level groups in dynamic events. The panel took this opportunity to introduce GW2's side-kicking system. If a player has a high-level character who has gone back into low-level territory, that player will be side-kicked down to the appropriate level for that content. This will allow players to adventure with those of a lower level without having to create an entirely new character. In addition, high-level characters can side-kick friends up in level so that they can adventure together in the later areas of the game.
And 10 minutes of combat:
