I think you're missing the point: robots.txt is generated on-the fly by a script here, and different user-agents see different robots.txt directives. If you are a genuine Googlebot from a valid IP address range, you don't see the "Disallow: /" at all.
If you are a browser, you get the "bot blog page."
