I don't think this was a poor choice. With all due respect, I think you are reading way more into Kirk's line about his death than was ever intended or than most people would ever think about it.Which is my point -- that human writers are fallible and we have the right to criticize their poor choices.
Kirk thought he would die alone in the end. That's it. No metaphysical powers involved. Kirk has always fought a battle with loneliness. And he also trusted that if his companions Spock and McCoy were there, they'd pull his ass out of the fire. It doesn't have to go any deeper than that.
