> It's staged shocking also - cows first hear beeping / buzzing, followed by mild shocking - less than a regular electric fence, then a greater shock

Yea, that’s basically exactly how the electric fences people have used for dogs for decades work.

Sure - save for the "live updates of boundaries" part -

the worst case fail situation here is likely a boundary being broadcast that was on the opposite side of the planet ("a simple error of plus/minus sign") and the entire herd is constantly(?) being buzzed and shocked.
