This page is testing wethether nosnippet can force anything.
A snippet is a text excerpt from the returned result page that has all query terms bolded. The excerpt allows users to see the context in which search terms appear on a web page, before clicking on the result. Users are more likely to click on a search result if it has a corresponding snippet.
If you wish to prevent Google from displaying snippets for your pages, use the following tag:
<META NAME="GOOGLEBOT" CONTENT="nosnippet">
Note: removing snippets also removes cached pages.
