I'm going to approve this, since I think the logic is more right with your change. However, it makes me uncomfortable about the fragility of this code snippet, since it isn't tested. Clearly the buggy code wasn't found when the original change was made. Too bad we don't have doctests for the internal documentation.
Not your problem though, and thanks for your contribution!
