Yeah, it's a funny mistake, but what he meant, is what if the US Treasury Department declared bills with serial numbers containing "7" invalid. That would indeed complete the analogy. And it's a sharp example -- because money is conceived of as fungible, one $100 is as good as another, so two $100 bills compare as equal, whether they are equal or not. Of course, the counter argument is that it's not unlike counting a reflection of a $100 bill as another $100 and concluding that you have $200 (you need two mirrors to double your money, technically ;-)). I don't think there's any way to make it "more logical" -- it's going to break somewhere no matter what assumption you make, so you just have to learn what's really going on in order to avoid confusion.
