Right. Because the CA only verified your control of the domain 
that it issued the cert for; if you get a cert for fredsmith.com 
and could use it on a server that impersonates www.amazon.com 
you could steal billions of dollars from millions of people.

And an added point which is not obvious to some people,
it's only implemented for one level. *.domain.com works 
for www.domain.com ftp.domain.com silly.domain.com but 
NOT www.foo.domain.com . Even though this wouldn't actually 
violate the trust constraint in any situation I can imagine.
