This means that a 10 star general gives +10(!) morale. Generally elite units like knights and the like have base morale=8. This is already quite high. However enything above about 14 makes units unroutable, and this is pretty easy in the SP game as the discussion so far should clearly show. These are the infamous "jedis".
Units do not get the morale bonus from the valour obtained from the general's command star bonus. The bonus is obtained directly from the command stars and and centres around the general himself. Once those units stray outside a 50 metre radius, the morale bonus is effectively cut in half.

That's how I understand it as well.
