In the Northeast, where houses and lumber expand and contract with the changes in the weather, an over stapled condition "could" trip the AFCI c/b if the staple creates a path between the line to neutral or line to equipment ground. Haven't seen it occur but theoretically, it could happen.
That's one or two steps past a simple tightly nailed staple.
Some think the tightly nailed staple is a culprit in itself, which it's not.
