This is the nonsense that the CEO "union" of cross shareholding and executives serving on other boards leads to. The CEO sets the overall business strategy with the advice of the board. They then have to delegate that strategy to their subordinates for the different activities necessary. It's harder to find skilled workers with specific skills than it is to find a generic "CEO".
