Proof step 23 from proof reduce-unique (previous step)

C[t3] = C0[S _ v1 _ v2 _ v3], value(v1), value(v2), value(v3), context(C0), context(C), (∃ v1, v2. t3 = K _ v1 _ v2 ∧ t0 = v1 ∧ value(v1) ∧ value(v2)) ∨ (∃ v1, v2, v3. t3 = S _ v1 _ v2 _ v3 ∧ t0 = v1 _ v3 _ (v2 _ v3) ∧ value(v1) ∧ value(v2) ∧ value(v3)) ⊦ C[t0] = C0[v1 _ v3 _ (v2 _ v3)]
