The middle switch position selects just the middle pickup. The first and last positions select the bridge or the neck pickup. The 'in between' positions pair the middle pickup with either the neck or the bridge pickup. The middle pickup is out of phase with the other two, giving that characteristic 'hollow' sound.

As for the kind of guitar, I've heard one guy nail that sound really well, and he had a mid-80's Strat with that switch mod. I also believe that two people playing the same gear still sound like two different people, so I have to attribute a lot of that tone to the player.
