Does the main domain tag audit automatically include sub domain tag audits?

SiteAudit is configured to start at one or more URLs and crawl through a site from that point auditing every URL to a specified page depth. Typically we will crawl subdomains with the default filter. To exclude all subdomains other than "www" check the box on the audit setup page to "Exclude Subdomains".

To only audit a specific subdomain, blog.example.com simply list this as the only starting URL. We will automatically audit only this specific subdomain.
