The ground is grounded in the headphone jack.  If RF currents are using it as an ingress point, then those currents are looking for a path to a lower ground potential.  If they have nowhere to go, they stay in the radio.

RF via the headphone jack is a very rare thing for Flex radios (I cannot remember one incident of it).
