Unless I misunderstand something, fantisicsm effects all the soldiers so casting it four times in the same battle round is equivalent to casting it only once.

Nope. True, it affects all soldiers, but each casting simply increases morale / decreases morale loss somewhat - from what I understand, Sermon of Courage actually gives a greater effect, but only within the area of effect. So if your army was suffering sufficient morale loss, it may have seemed reasonable to the AI to chain cast fanaticism. ( If it hadn't, your army might well have routed quite rapidly. )
