Aye haha, hes depicted Shanks a few times like that now. It cannot be coincidence at all, tis definitely some kind of intentional foreshadowing.
He's holding off on showing us how he will deal with Bartolomeo too, but given how he handled Kidd and how he's been said to have a truly unstoppable, fearsome rage/wrath and hates his friends being hurt, Shanks really might go savage mode on Barto too.
This is way too damning for me too, ain't no way this is coincidence too:
Shanks started off the series with one of his crew instantly killing a bandit with no hesitation. "In cold blood" even. Shanks and his crew are laidback, funny, chill, goofy but when shit gets real, they are merciless and serious as fuck.
