The further lens is from the camera the closer it can be for shortest focal distance. So example: say normally you have to be 5 feet away for the minimal focusing distance. With the Bellow now you can be 1 foot away.
For the reserve lens, basically when when switch which way the lens is pointing you get a magnification effect because by default, the side that is suppose to face the camera sensor is only an inch away at most.
Add them together and you get a nice big magnification.
