Proof step 1 from proof rg-blocked2-not-r2-unfair (conclusion)

[:S | [PL R1(pm, S', S'') -+-> (last ⊃ Post1(pm, s1, S);G1(pm, S, S'))] ∥nf [PL S = s]], RG-restr(pm, R1, G1, Pre1, Post1, I, R2, G2, Pre2, Post2), R2(pm, s0, S), ¬ R2(pm, s0, s), I(pm, s0), Pre1(pm, s1), Pre2(pm, s1) ⊦ (R1(pm, S', S'') ∧ R2(pm, S', S'')) -+-> (last ⊃ Post1(pm, s1, S) ∧ Post2(pm, s1, S);G1(pm, S, S') ∨ G2(pm, S, S'))

And obtained the following new goals

Proof step 2:
