What difference does his suit make? Given that he’s not grounded, and he and the helicopter and the wires are all at the same potential, why does he need the suit?

I’ve heard that without the conductive suit, there’s an uncomfortable tingling sensation due to the very high electric fields around the cables. The suit helps prevent voltage potentials across the body. The Discovery Channel movie “High Voltage” had some discussion about this, along with a similar video.
