At an abstract level - when WAN is off the on to off switch is simply a command to make the screen white and then take the system into a low power mode, instead of letting some time pass until the screensaver is drawn and the system automatically goes into the same low power state as "off".

I have noticed a major difference between turning off and sleep mode. I always keep WAN off.. probably havn't turned it on in over a month. I get two more weeks out of it if I leave it off. Then again, I probably only use it no more than 2 hours a day, so not sure if that has anything to do with it...
