@victorges @j0sh Hi, Could you please review this PR at your convenience? Thank you very much.

Hey @quantpoet thanks for the PR, I am inclined to leave it as-is with the explicit if because the comment nested within that becomes inaccurate and potentially confusing otherwise. If there is a better way to reword or explain things then I'm happy to take another look.
