Proof step 11 from proof getbar-union (previous step)

st .refs ∩ st0 .refs = ∅, r ∈ st0 ⊦ getbytearray(r, st ∪ st0) = getbytearray(r, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ ¬ r ∈ st → getbytearray(r, st ∪ st0) = getbytearray(r, st0)
Proof step 10:
¬ ¬ r ∈ st, st .refs ∩ st0 .refs = ∅, r ∈ st0 ⊦ getbytearray(r, st ∪ st0) = getbytearray(r, st0)

Rule argument

[crewrite-arg: getbar-union-01, F, [st0, st, r] → [st0, st, r]]
