Correct on salary unless he is performing some function in an employee capacity.

Resigning from board means very little while he's majority shareholder.

On final point. He may need to put some shares into another company in order to get funding from the money men he's talking to about the US club. They may want a Man City style parent company that owns stakes in multiple clubs. New York City, Man City, Melbourne City etc.

City Group - United FC Group? Pretty obvious where the name change inspiration came from.

As to who it benefits, only time will tell.
