Redirecting ?q=PATHNAME URLS to Appropriate alias?

Okay, I've just discovered this little gem, which I was hoping would keep me from having to use .htaccess, and manually write out a rewrite condition to handle this.

From item #4 on the feature list:

Checks if the Clean URLs feature is enabled and then checks the current URL is being accessed using the clean method rather than the 'unclean' method.

It's my understanding that this would appropriately redirect
site.com/?q=services/something/page
to
site.com/services/something/page

Am I wrong in thinking this is what that meant by saying the "unclean" method?
Anyways, it does not redirect for me in the way I expected in this situation.

Works great for redirecting the home node, and removing trailing slashes, but appears to not really help for avoiding duplicate content unless it redirects the ?q= urls appropriately.

Thanks for any help in advance.
