In underdoped hole cuprates the screening charge converts the charge density in the metallic-plane unit cells in the vicinity of the $\\mu^+$ to nearly its value in the insulating state. The current-loop ordered state observed by polarized neutron diffraction then vanishes in such cells, and also in nearby cells over a distance of order the intrinsic correlation length of the loop-ordered state.
