I would prefer to take the boolean definition outside and open a nested scope to avoid unlocking early. I think it is less future error prone.

As a personal preference I would move this upfront and avoid the else.

Anyway, this seems to be quite unrelated and I would recommend to land it in a another no-brainer bug.
