You can be sure that whomever was involved with the bug will probably never make that mistake again.
We all like the story of "just spent a million dollars training you", but experience tells me that there is absolutely no assurance whatsoever that any random person won't be repeating that mistake in the future.
EDIT: and to be clear, of what tiny bit I know, I blame test more than dev. From the dev side I can see someone making a stupid mistake (that for the record I could just as easily make) swapping the foo with the bar, or some mis-click in IB. But I'm still astounded that this made it out of test without getting caught.
