The first quoted rule is about subdomains. I thought we were talking about independent domain names :(

The only reason I noticed it was because I just started developing it and took it live with no files. I was mainly just asking if this is normal behavior? I guess it is right? It redirects to folder if no index.

I'm now inclined to say that I was right-- by accident at least-- and the whole question really is a red herring. If you're got live domains with no content, and people are getting redirected to your primary domain, that sounds very much like something the host is doing. Nothing to do with your htaccess at all. The alternative remedy in shared hosting is to populate each named domain with a placeholder page, which will be ignored if the site has an appropriately named index file. (As far as I can tell, it's a real physical file. It doesn't disappear unless I manually delete it.) The config file probably has something like "placeholder.html" as the last item in the DirectoryIndex list.
