I can see the change has been committed, but who has actually reviewed it? The change description doesn't say what the change actually does, so one can't say whether it is correct or not. At least an example of incorrect code produced ought to be shown and how the change affects it. As it stands I have no idea what is going on here, and surely no one who looks at it in a few year's time will. Change descriptions cannot be retrofitted, so I think the original fix ought to be reverted and, assuming it is indeed the correct one, reapplied with a correct change description (after a proper review).
