A clever captcha

I was posting a comment at James Newkirk's, and noticed a clever captcha implementation:
First, you don't see it. You write your comment and publish it. I guess all the spam bots are satisfied by now.
Then, after publishing, we are presented a final step, the captcha. This after-publish-step solves a sometimes experienced problem of mine: Lost comments due to captcha problems.
