rfc3265 discusses a subscription dialog.

The following quote that you provided explains
that BYE can close INVITE established dialogs.

In addition, the CANCEL can close
INVITE established early dialogs.

Sending a SUBSCRIBE with Expires: 0, closes
subscription dialogs.  Sending NOTIFY with
Subscription-State: terminated, closes
subscription dialogs.

A proxy refusing to proxy any more messages
will close dialogs which expire.

Returning a 481 to a request communicates
that a dialog is unknown.  It will lead to
explicit or implicit closure of the dialog.

The "In this specifications" text is meant to
convey that the BYE closes the associated invite
established dialog and the session created by
the invite established dialog.
