How is this better than just mapping GPS data to a hexagon and sending that to the third-party?

I think it is spoof-resistant from the sound of it? You giving a valid proof-of-region via one of their circuit designs provides proof of your region but does not give your exact location, from the sounds of it.

I'll get back to you after I've read through it.

Yes, looks like the actual advantage (or disadvantage , depending on who you are) is ensuring that you don’t send a false location to a third party.
