Proof step 8 from proof disjoint-nopath-both (previous step)

path∃(str, r0, r2, st), path∃(str, r, r1, st), disjoint(str, r ' + r0 ', st), path∃(str, r1, r2, st) ⊦ r = r0, r1 = jvmref, r2 = jvmref, disjoint(str, r1 ' + r2 ', st) ∧ r1 ≠ r2

User applied rule insert rewrite lemma

And obtained the following new goals
