What it does is instead of giving you just a portion of a page to edit when your site is closed it will give you an entire page to cusomized. Basically when your site is closed you can hide everything from the visitor. For example a completely blank page, or just a page with an image on it. Remove header and footer. You have complete control on what is shown to anyone who visits your site when its closed.

The default vb feature only gives you the center of a page to edit with the header and footer and style all visibile.

I do this becuase alot of visitors still try to go into their accounts and make changes or just still try to navigate teh site in some way. Since you able to change the entire page that they see you can stop them from doing or seeing anything.
