Only in the sense of a higher resolution output it does provide anything with a semblance to power is what I believe - and it has been confirmed from the spec sheet of the devkit that while the tablet itself gives 720p output, docked, you get 1080p.
Mind you, I didn't watch the video. However, "some games playable" only when docked would torpedo Nintendo's whole idea for this thing, If the dock did give additional power, it could be in the form of nicer textures, or more effects.
