If he doesn't disconnect them, or alternatively wire through the walls to get to the faceplate of the proposed NTE5, he is going to have star wiring. On top of two masters anyway.
I don't like the sound of that.

The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
