exactly.Using a GEC from the Meter to a ground rod ( or any other Ground Electrode ) and another GEC from the Main disconnect enclosure to the same Ground Electrode (GE), ( remember all GE's are to be bonded together) those GEC's will provide a parallel path with the grounded conductor.
In general, it is difficult for Service Equipment not to have a parallel path for the grounded conductor if more than one GE or more than one GEC is used.
