The Group Icon shows two players teaming up on a Stadium-Mode Mii. I think the large "Smash" icon brings you straight to the standard Smash mode, and the "Group" option under "Games & More" is for other multiplayer modes like multiplayer Stadium modes or multiplayer All Star Mode like Brawl had. Maybe they'll even have a multiplayer Classic mode this time?
