In an emergency the helicopter can just drop the load: the pilot can release the hook and fly away. Unlike carrying a casualty, this is unlikely to be anywhere near as dangerous. If the tower is somewhat bolted on, it'll probably stick there long enough for the other bolts to go in. Worst case, it tips over and falls to the ground, but in any case it's unlikely for there to be any injuries.

As far as I know, one of the reasons why dropping the load is considered dangerous is that the line that was holding the load will be suddenly released from high tension, so it will go flying at fast enough speed to injure someone.

Drop the load while there are hardhats waiting on the ground below? Uh ya that's probably not happening here.

Did we watch the same video? There were people below that helicopter quite often. I'm not sure how you'd go about just dropping the pole.

They are referring to releasing the load when it's connected to the ground through the tower. Meaning some bolts are in place, therefore is probably unlikely to tip over.
