The "faked" shots (apart from the image stabilization simulation -- which all of the major camera makers have done in ads at one time or another) were done with actual hardware/firmware prototypes, so although they weren't done with production samples (which didn't exist at the time), they were "real" in the sense that they used the same sensor, processing pipeline and optics as the production camera.
I thought the night time shots were also identified as being faked, and, in fact, the aperture of a smartphone camera wouldn't have the same sparkling effect as a SLR (which actually took the picture) - so the pictures were different as well.
I think he is referring to the photos that they displayed on the day it was revealed. The pictures are there on nokia site and are equaly impressive. http://www.nokia.com/global/products/pureview/
