  It is shown that an account for the space separatedness of the two-orbital
subsystem of the oxygen holes and the subsystem of the localized spins of
copper ions in high-T$_c$ cuprate superconductors leads to the stability of the
superconducting $d_{x^2-y^2}$-wave pairing towards the strong Coulomb repulsion
between holes located at the nearest oxygen ions. This effect is due to the
fact that the Coulomb potential slips out of the equation for the Cooper
pairing in the $d_{x^2-y^2}$-wave channel owing to the properties of symmetry.
