Sessions are (usually) stored using cookies, and cookies are domain-specific. So, it doesn't matter if google.com or evilhackerdomain.ru uses the same session name as your app; your cookies are only readable/usable by the domains you specify. Even in the unusual scenario that sessions are managed in some other way, it will be domain-specific.
