Such a current would be applied downstream of the RCD. If the RCD trips, or is used as a point of isolation, and the arrangement tries to apply current, you are left with a current which might have nowhere to go except the person to whom additional protection is being offered, or whom the isolation was intended to protect.
Yeh but it is such a tiny current originated through a big, erm, high value resistor.
