Proof step 13:
⊦ bor(band(s2i(sho1), bcompl(b2i(by2))), band(bcompl(s2i(sho1)), b2i(by2))) = s2i(i2s(bor(band(s2i(sho1), bcompl(b2i(by2))), band(bcompl(s2i(sho1)), b2i(by2))))), bcompl(b2i(by2)) ∈short, s2i(i2s(band(s2i(sho1), bcompl(b2i(by2))))) = band(s2i(sho1), bcompl(b2i(by2))) ∧ s2i(i2s(band(bcompl(s2i(sho1)), b2i(by2)))) = band(bcompl(s2i(sho1)), b2i(by2))
