No, changes are only applied to the templates for the MyBB theme. Any themes that inherit from the MyBB theme and change templates at all need to apply those updates manually. We cannot apply them manually if a template has been edited from the standard MyBB theme as we might break people's themes then.
The "Revert to Original" will revert any modifications to a template (including those done by your theme's author) to make the template the same as the MyBB default theme. You probably don't want to do that.
