Raising the ISO doesn't increase noise -- using a more narrow aperture and/or faster shutter speed increases noise.

"Raising ISO sensitivity amplifies the electronic signal, which also amplifies any noise in the signal; as a result, the higher the ISO sensitivity, the more obvious the effects of noise on your photographs. The same is true of all digital cameras."

I think what he meant was that raising ISO in itself doesn't add more noise, but yes it gets amplified.
