If there is a ground fault in the circuit being supplied from the generator, the 100,000 ohm resistor will limit the leakage current to about 1.2 mA (less than the 5 mA level of most ground fault circuit interrupters) to minimize the shock hazard. Since the leakage current is below the threshold of GFCI protection, the GFCI protection (either external or built into the EVSE) will not activate.
A solid bond makes the circuit equivalent to plugging in to a non-GFCI receptacle in the house. Therefore, there is no personnel protection unless GFCI devices are used (either external or built into the EVSE). I recommend the resistor connection for most applications since it does not depend upon GFCI tripping to prevent shock hazard (that is why most portable generators are floating).
