Yes, urirhssub in SpamAssassin 3 will check every visible URI, even if it's mentioned within a redirector:
http://some.redirector.com/blah/blah/http://some.othersite.com/
Both redirector.com and othersite.com above would get checked, and including some variations on those. But http://tinyurl.com/blah won't get the redirected-to site checked since it's invisible in the original message.
Perhaps the SpamAssassin and SpamCopURI authors can provide more detailed info, corrections, etc. on the above, but the quick answer is that some provisions for checking redirected-to sites is already in place.
SpamAssassin is currently limited to identifying redirectors that require 'http(s)' to be in the URI. So it won't detect domains redirected to by the zdnet redirector and any other similar ones.
