That is a good safety measure. The gases escaping from a charging battery are explosive. When the final jumper cable connection is made (OR unhooked) it will generate sparks. If the sparks are close enough to the battery/escaping gases it can cause the battery to explode. Fairly rare, but not something you want to have happen, battery acid blown all over you and the car can make a bad situation much worse.
