the way it works is that 1 word is "known" and one is "unknown"
if you get the "known" word right, that's all you need regardless of what you type for the second
the "unknown" one gets answered by you and many others, and an algorithm helps figure out what the unknown word would be. Once it's known, it's fed back into the captchas as a "known" word.
as far as a computer science research project, recaptcha is one of the best idea's I've seen in a long time... but as a security measure, it's still very flawed though
that, along with the fault tolerance, would be why you're able to guess so loosely :p
