As Geoschmo said the secondary strategy only works if the first is impossible. For example, I created a strategy so that my ships would ram enemy vessels. Ram is the secondary strategy and firing point blank is the first. The ships will only ram when they have been damaged so that they have no weapons left. Works quite well, the ships can no longer serve their primary purpose without weapons so they do the only thing they can and take the enemy with them.
