...one domain at the top with eight bullets under it...
Those are called Sitelinks, and I can see how you can assume that's what we've been talking about. Sitelinks are extra category links that appear under some top listings in Google. They can be either two columns with bullets, as you describe, or they can be mini "inline" Sitelinks... several links in a line.
See this discussion for more on those....
Sitelinks Information - a reference thread
What we're talking about in this thread are full column width listings of three or four lines, including basically a hyperlinked title, a description or "snippets", and a url.
Previously, Google had limited the number of such listings to two per domain, unless you used the site: operator to list many pages in a site.
Recently, Google decided that if you include a domain or company name in combination with a keyword in a search, you are signaling strongly enough that you want to see listings from a particular domain that Google is showing more than two results per domain, in some cases many more... and occasionally eight.
I've routinely used this syntax as a quick way of bringing up a keyword search in combination with a company, and Google's new approach doesn't seem unreasonable. If I were a retailer selling Apple iPods, though, I'd definitely be upset, because apple.com is now dominating the page, and since Wikipedia and Amazon and cnet take up the remaining spaces, other iPod vendors are getting shuffled off to page two, at best.
Google's about to change the default number of results on a page, probably to 20, but that still puts Apple up top for most of the results. That's what the discussion is about.
