question about switch wiring

[wef200]

When looking for directions on how to hook up a bypass with a millenium 2 circuit and a dpdt switch. I came across this link that had a diagram, the wiring seems wrong to me shouldnt the effects output be hooked to the empty slot on the switch, or is this correct. There is nothing that ever connects to the led circuit ever. The link is here http://www.diystompboxes.com/pedals/dpdtled.JPG.
