The blog post you linked to (from my blog) instructs to set up a new VirtualHost element with an ip of 127.0.0.2 so you can create multiple subdomains easily.

You're setup using 127.0.0.1 will work great for one subdomain, but if you plan on adding more, I'd suggest setting up the new VirtualHost elements as described in the post.
