"Or else" means: if there were production of distinction in the Self, then because the distinction would be of the nature of the Self, the Self too, being non-different from it, would be impermanent like the distinction. But if the distinction were something separate [from the Self], it would not be logical due to the impossibility of connection—this has been discussed hundreds of times.
