From what I gathered, the idea was supposed to be that when fighting broke out, the hostages would know that the fighting was a rescue mission and be able to act accordingly. Imagine if there was just suddenly fighting, with no context; hostages would /know/ the FARC was on edge and would be extra careful not to try anything stupid and get killed. However, with this message, they would know that the fighting is a sign of a rescue mission and try to escape.
