It seems to me, that for some time the GB has emphasized itself as the head of the Jehovah's Witnesses, and the distinction between the religion and the corporation. In times past it spoke of "Jehovah's Witnesses using the WTBS to publish its literature." The Christian Congregation of Jehovah's Witnesses is a separate legal entity, responsible for administration of the religion.
What this means (in my view) is that the Watchtower Society could go bankrupt, and the GB could survive like a snake shedding its skin. The Christian Congregation would need to establish a new legal entity to handle some matters, but it could be done. It happens all the time in the business world.
