Are Sites Created From Blog Templates Always Connected To The Template?

Hello,

When a new site is created using the plugin New Blog Templates, are the sites created in this manner always connected to the Blog Template?

For example, after creating a site based on a new blog template, if I change the template site does the change flow out to all sites created from the template site?

If so, how do I disconnect a site from the template site so that changes to the template site no longer affect the site created from it?

Thanks for clarifying.
