WPMU fedburner redirects via htaccess

Hello,
I would like to setup to redirect feeds of wmpu webs to feedburner. I found nice advice to do thet with htaccess.

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} !FeedBurner [NC]
RewriteCond %{HTTP_USER_AGENT} !FeedValidator [NC]
RewriteRule ^feed/?([_0-9a-z-] )?/?$ http://feeds.feedburner.com/wpbeginner [R=302,NC,L]
</IfModule>

But it is only for single wp, is it?
Can you help me how to setup if I have more webs on wpmu?

Is this right? Example of redirection of main web and subdomain?

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} !FeedBurner [NC]
RewriteCond %{HTTP_USER_AGENT} !FeedValidator [NC]
RewriteRule ^domain.com/feed/?([_0-9a-z-] )?/?$ http://feeds.feedburner.com/domain [R=302,NC,L]
RewriteRule ^sub.domain.com/feed/?([_0-9a-z-] )?/?$ http://feeds.feedburner.com/sub-domain [R=302,NC,L]
</IfModule>

Thanks,
