WereKitten is right, the emulator renders games at 720p (thought it might use some tricks to do it depending on the game).
It's the same thing the 360 does to Xbox games. It takes the commands that the games give to the Xbox GPU (things like "draw this polygon" or "put this texture on this object") and uses the 360 GPU to perform those commands at a higher resolution. The emulator can also render with additional anti-aliasing which the emulated platform isn't capable of.
It's better than upscaling. Upscaling is just rendering at some resolution (480p in the Wii's case) and then "zoom in" that image to get a bigger one with more pixels.
