Proof step 6 from proof precise-sep (previous step)

H2 ∪ H0 = H1 ∪ H, ((P0 * P1))(H2), ((P0 * P1))(H1), precise(P1), precise(P0), H2 ⊥ H0, H1 ⊥ H ⊦ H2 = H1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 7:
⊦ ((P0 * P1))(H) ↔ (∃ H0, H1. H0 ⊥ H1 ∧ H = H0 ∪ H1 ∧ P0(H0) ∧ P1(H1))
Proof step 8:
H2 ∪ H0 = H1 ∪ H, ((P0 * P1))(H2), precise(P0), precise(P1), H1 ⊥ H, H2 ⊥ H0, ∃ H0, H2. H0 ⊥ H2 ∧ H1 = H0 ∪ H2 ∧ P0(H0) ∧ P1(H2) ⊦ H2 = H1
