Probably it's just because of my limited experience with the optimizer
but I don't find the proposed change particularly straightforward. I
would suggest adding a comment before the Assert's and/or a detailed
commit message would be helpful.
Other than that I can confirm that both branches in the Assert's are
executed and the tests pass in different test environments.
