It matters less if it's actually true than if someone trying to pull off the scam thinks it might be. The only way to find out if that hole exists in the system is either to have an insider tell you that it would, or to try it out...
Oh, and to add further to the nonsense: the product description technically doesn't say that what you're buying is a pair of shoes. So a sufficiently automated system might mistake a single shoe for a legitimate product. It's absurd, but not impossible to see how you might end up there.
