I changed the explanation because, well, it was ludicrously wrong.
I have changed it as well. It used to say "Whoever wins this bet wins double the original bet amount." This is wrong, only the previous winner gets double. If the previous loser wins, then both are "even" and no one wins anything, hence the term "nothing"... aka, the original winner EITHER wins double OR nothing...
