Well, one thing there isn't accurate: the part of the nail that's exposed (the part that came through) is not doing anything to secure the joint. Only the part of the nail that's buried in wood contributes to the joint (unless the nails are clinched over, which is not and should not be done for roofing, never mind that it would cost a fortune).
Because they definitely do NOT want the nails to be too short, and because the thickness of roofing materials and decks varies, and because there's no harm of any sort in using nails that are longer than the bare minimum, roofers use a length of nail that will always be long enough.
Actually, it's my understanding, after asking this very question, that the part of the nail hanging below the sheeting does in fact help secure the nail from being pushed out when the wood expands and contracts with changing temperature and humidity. The wood can contract and expand but it can't push the nail.
And if they use galvenized ribbed nails, the part of the nail hanging below does oxidize over time and help prevent it from wanting to come back through.
The roofing nails aren't the biggest issue there's common wood nails sticking out 2 plus inches all over the roof. Seems like when they tried to attach the planks to the frame they frequently missed.
In this case, sometimes the nail is a lot better than the hole, or the damage done to the sheeting from removing it.

I'd be willing to bet that those are all roofing nails. If it truly is sheathed with planks and not plywood, it would be hand nailed rather than with a nail gun. There's no way a carpenter would miss the joists all over the roof.
If there is more than one layer of shingles they would use longer nails for the 2nd layer, or at least they should. As has been said many times, the only problem here is when you lift your head up too high. The good news is you'll only do that once or twice before you catch on.
If your Attic access point puts you near the sheathing with nails, go to the home improvement store and buy a piece of 1” or 2” rigid foam insulation and stick that up there using the nails and/or glue. Don’t do it all over, unless it’s covered by non flammable foil or something else, but one little piece won’t hurt anything
