It's not the equipment that makes the image, it's the photographer behind the equipment. Give credit to the man with the imagination and courage to do something different.
Interestingly, the very fact he used a point and shoot for this actually helped for many of these shots. The small sensor on a point and shoot that makes it so hard to get a shallow depth of field also makes it very easy to get a deep depth of field which makes these photos look so realistic, despite combining a subject that's only a couple of feet away with a background that's 100+ feet away.
Getting the same result on a DSLR would have required the right lens, a very narrow aperture, and a very carefully set focus point. Getting the same result on a medium format camera would likely have been impossible without taking multiple shots at different focus settings and 'stacking' them in post-processing.
For example, a typical point and shoot at 28mm equivalent, f/5.6 would be able to keep everything in focus between 1.5 feet and infinity in a single shot -- pretty much any point and shoot will do this happily. To get the same result on a crop-frame DSLR would need a 18mm lens at f/21. On a full-frame DSLR you'd need a 28mm lens at f/32 (which you'll struggle to find), and on a medium format camera you'd need a 48mm f/56 lens (which doesn't exist).
In this case, a point and shoot camera was almost certainly the right tool for the job.
