This is not true, it is a lube howbeit a very thin lube that doesn't last long, while the WD does stand for water displacement it also has some lubricant qualities to it...not really suitable for lubing a bicycle chain though it work in a pinch.
Straight from WD40 manufacture to your eyes, read:

While the above site does say it's fine to use on a bicycle chain I wouldn't use it, it's way too thin, but in a pinch it will work, drip some onto a chain, wipe the chain real well, and let it dry overnight and your good to go the next day...however after that ride you will have to reapply after each and every ride.
