That's sadly not correct.

For example using "beast mode" on the front page search, a good portion of the domains are "handshake" entries with only a tiny little (i) button to distinguish them from actual domain names which could be used in the real world.
I can add them to my cart with no other mention that the product I am buying is a sham, I can even add a SSL certificate along with my purchase- which can't actually be issued because it's not a real domain name.

This feels like an incredible understatement. They will never be accessible by anybody who doesn't install software explicitly with that goal, they will never be able to receive email, nobody is going to issue SSL certificates for them.
