The point is that after you search for a domain at netsol.com, you get a Network Solutions landing page: "This Domain is available - Get it Now!", they effectively squat every domain that's searched -- for presumably a 5-day refundable period -- and in the process lock-out every other registrar from selling it.
Here is another domain which is mentioned in the comment thread: http://networksolutionssucksballs.com/ , someone searched for the name and it already has a Network Solutions landing page, and though you can buy it, its 'taken' if you try to buy it from another(cheaper) registrar.
You can try it out yourself, it takes around 15 minutes after you searched a domain for them to register it and appear with a NetSol landing page, instead of timing out.
And BTW, the person that bought the youguysseriouslyregistereverythingisearch.com domain to squeeze some Adsense clicks while its making headlines is registered to:
