htaccess question: is this correct?

[eluser]codex[/eluser]
I'm testing my server on the implementation of wildcard DNS. I'd like to know if these conditions in the htaccess do what they're supposed to. If I'm correct, any request for a subdomain on scripto.nl should redirect to www.google.com. Right?:

Code:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.scripto\.nl?$
RewriteCond %{HTTP_HOST} ^([^.]+)\.scripto\.nl?$

RewriteRule ^$ http://www.google.com
