This section of the getting started guide is there to show examples of how to go about customizing page. It is showing how to make use of the bindings and DW's interface to get values onto the page where you would like to see them.
You can design and lay this page out however you would like it, then just drag and drop the bindings onto the page where you would like to see that detail information. For user registration pages you would normally use SecurityAssist to generate the front end pages for registering, logging in, and updating the profile. DataAssist does a good job of creating the back end pages though for you to manage the users.
