Where are the URLs in Google top ads coming from?

I'm not sure if this new but I noticed it today:

Some of the ads that are displayed on top of the SERPs have a title, and then their web address, separated by a vertical bar.

For example (see image): Coffee Beans Online | CoffeeBeansDirect.com

The same ad, when displayed in the side bar (see 2nd image) doesn't contain the web address. I expected that because if you count the letters in the ad, including the 'coffeebeansdirect.com' it exceeds the amount allowed for a google ad.

My question is: How did it get there? There's no room to distinguish between top ads and side ads when you write a new a new ad in adwords so where did it come from?

Plus, notice that both CoffeeBeanDirect.com and ROASTe.com use caps that are not used in the green link at the bottom. How did Google know to present the url that way?

I don't know how to trigger it, but Search Engine Roundtable wrote about this last month at http://www.seroundtable.com/adwords-title-url-13424.html. Google is quoted in a forum post as saying

When shown in the headline, the display URL will be separated from the rest of the text by a vertical bar and will include only the domain, not the "www." prefix or any subdirectories. Your display URL will also continue to appear as normal below the description line. Of course, if the headline already contains your domain, we won't display it again. Finally, it's possible for the display URL domain to appear in addition to a description line that is promoted to the headline, as long as the resulting headline is sixty-eight characters or less.

Thanks. Exactly what I needed.

But why is is that the display URL in the title line looks different from the green display URL? AS in ROASTe.com instead of roaste.com?
