Proof step 8 from proof wand-flatten (previous step)

((P0 * P1))(H0), H0 ⊥ H, ∀ H1. H1 ⊥ H ∧ P0(H1) → ((P1 -* P2))(H1 ∪ H) ⊦ P2(H0 ∪ H)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ ((P0 * P1))(H) ↔ (∃ H0, H1. H0 ⊥ H1 ∧ H = H0 ∪ H1 ∧ P0(H0) ∧ P1(H1))
Proof step 10:
H0 ⊥ H, ∀ H1. H1 ⊥ H ∧ P0(H1) → ((P1 -* P2))(H1 ∪ H), ∃ H2, H1. H2 ⊥ H1 ∧ H0 = H2 ∪ H1 ∧ P0(H2) ∧ P1(H1) ⊦ P2(H0 ∪ H)
