I don't understand it either; as others pointed out as well, I can't do a consistent signature even if I tried to (I've always had trouble with writing, and I barely do anything outside of shopping lists and a paper calendar nowadays).
I've always thought that as long as you can recognize your own signature and declare in a court of law, under oath, that the signature is or is not yours then it's fine.
It's still not foolproof though. An ex of my GF forged her signature and took out a loan in her name. They're still on her ass about that one, despite her claims that the signature isn't hers. They're not taking it to court though, they probably don't have a case. Doesn't stop them from harassing though.
