If you look at the source of that page, you will see that there is a <link rel="canonical"> pointing to the original post URL. This tells Google that the original URL is preferred, no matter what URL the page is accessed from.

> Hi guys,
> URLs with a dot, a colon, or many, still works and Google treats it as
> duplicate content. Here is an example:
> Original:http://ma.tt/2010/11/one-point-oh/
> With a dot: http://ma.tt/2010/11/one-point-oh./
> With a column: http://ma.tt/2010/11/one-point-oh:/
> With many dots:
> http://ma.tt/2010/11/one-point-oh...../<http://wplancer.com/a-beginners-guide-to-the-command-line........../>
> All of these URLs work and if mistakenly on the site, they will be
> considered duplicate content by Google.
> Is this a bug? If not, why is this happening?
> PS: I wrote about this in the support forums, but the post seems filled
