What exactly is meant by "No hostages beyond this point" is hard to discern. That message, posted on the inside of several doors in such fine establishments as Keagans State Jail in downtown Houston, greets anyone about to exit the jail and enter the lobby where visitors must turn in their IDs and be dressed in proper attire to walk through the doors. In fact, the words grace two doors, one right after another, so which point exactly, are the signs referring to? Perhaps the second sign is there in case you missed the first one. But who could miss such a warning, which implies that "Negotiating beyond this point will not work -- everyone will be shot."
