This is the second or third time I've seen 'backfiring' mentioned. Does
this mean the nail fired out of other than the head of the nailgun, or
what?

I assumed it meant that the gun appeared to fire normally, but he didn't see
a nail emerge, so he just figured it was a faulty discharge. I can't
envision a nail coming out backwards, at least not on my nailgun. Shoot
forwards and ricochet, yes, but that's about it.
