A registered shareable can only be added once to a site group. Once a registered shareable has been added to a site group, it is available only to members of the site group.
If a site group does not contain any sites, any shareable can be added to the site group. If the site group does contain sites, the sites in the site group cannot be in any existing site groups that contain this shareable.
