I'm 90% certain there's a button to drop the saw instantly. And the power won't route through the helicopter bc it's not grounded, whereas pretty much any ground based equipment would ground the current if it touched the wire.
They use these across tens of thousands of miles of power easements all the time. The easements need regular pruning to keep branches from touching the wires and starting electrical fires.

I know nothing about this, but I would imagine it's not a button, its likely mechanical. If the safety circuit detects an arc, the cable detaches.
