Same kind of stuff pop-out if you try to whois google.com, although sometimes it depends on the whois server whether it lists all the domains.
Looks as if whois name.com is (surprisingly?) not only looking up 'name.com' but every domain that starts (not: ends) with 'name.com', such as 'name.com.someother.com'.
It lists nameservers (which are also in whois in many TLDs) that start with name.com. In your example, name.com.someother.com is not an actual domain name that has been registered.
nothing to see here. its just showing that the query syntax for whois (in the wild) is broken.
Its showing name servers with hostnames that match the query. I first read about this on Slashdot in 1998 (okay, maybe I'm exaggerating that a bit - this has been making the rounds for years...)
