RF is AC ... whatever current goes toward ground comes back every half cycle.  It doesn't just go into the ground and disappear.  You aren't bleeding off a static charge that happens to be referenced to ground.

Dave, common-mode current in coax shield is no different than current in a dipole, say one low to the ground. If you connect a wire from any point on the dipole to ground, current will low. At least NEC thinks so!
