Proof step 5 from proof disjoint-nopath-both (previous step)

∀ r3, r2, r1. ¬ (r3 ∈ r ' + r0 ' ∧ r2 ∈ r ' + r0 ' ∧ r3 ≠ r2 ∧ r1 ≠ jvmref ∧ path∃(str, r3, r1, st) ∧ path∃(str, r2, r1, st)), path∃(str, r, r2, st), path∃(str, r0, r2, st), is_valid_ref(str, r2, st) ⊦ r = r0, r2 = jvmref

And obtained the following new goals

Proof step 4:
path∃(str, r, r2, st), path∃(str, r0, r2, st), is_valid_ref(str, r2, st), ∀ r1, r3, r4. r1 ≠ r ∧ r1 ≠ r0 ∨ r3 ≠ r ∧ r3 ≠ r0 ∨ r1 = r3 ∨ r4 = jvmref ∨ ¬ path∃(str, r1, r4, st) ∨ ¬ path∃(str, r3, r4, st) ⊦ r = r0, r2 = jvmref
