Bah! Google index subdomain rather than the real domain!

So I have created a directory of pr1.domain.com and placed

Code:

RewriteEngine On
rewritecond %{http_host} ^pr1.domain.com
rewriteRule ^(.*) http://domain.com/$1 [R=301,L]

Within it as an .htaccess file.

My question is will google update the url in its directory based on that file?
