Proof step 10 from proof unique-elems-subset (previous step)

∀ n. count(n, bag1) ≤ 1, ∀ n. count(n, bag0) ≤ count(n, bag1) ⊦ count(n, bag0) = 1, count(n, bag0) = 0

User applied rule all left

And obtained the following new goals

Proof step 11:
count(n, bag1) ≤ 1, ∀ n. count(n, bag0) ≤ count(n, bag1) ⊦ count(n, bag0) = 0, count(n, bag0) = 1
