I thought it was probably around that area of temp, for me personally I'd find that a bit too smooshy, I prefer my pulled pork to have a bit more texture still, so I take it to 85C generally, maybe up to 90 if it feel like i's a bit too firm. Yours certainly looks fall apart tender though.
There's no "perfect temperature" and you have to go by feel and instinct. I'm pretty new to this so I'm still learning This was a very cheap piece from Costco and it had very little fat which isn't my preference. Next time I'll buy a much better quality cut (preferably with the bone still inside) and see how it comes out.
