It ends up being the most fault-tolerant way of navigating to a site. In the address bar, a typo will either not resolve (which takes several seconds) or it will resolve to a site designed to funnel traffic from the misspelling. Also, you general don't need to type as many characters into the search bar to get to the site as you do if you use the whole URL. All in all, typing the site into the search and clicking make quite a bit of sense from the usability standpoint.
