I was under the impression that such a person wouldn't care because knowing that water seeks it's own proper level under any and all circumstances, each living being is in exactly the spot they are supposed to be in.
If I understand what you are saying, it would seem to follow that there is not much of a point on even having a Dhamma in the first place.
Therefore I would imagine that they would believe that a being's proclivities attended by an uninterrupted progression of circumstances that transmigrate from life to life over countless lifetimes are exactly what each being has to deal with at the moment.
I don't think that is or can be made compatible with Buddhadhamma. For one thing, it seems to rely on a direct denial of Anatta.
But there is a more serious flaw to that idea: it encourages callousness and disregard of moral duty.

have seem similar ideas being taught by Kardecist Spiritism. Which is one of the reasons why I am so fiercely critical of that so-called doctrine. I have seen first hand how quickly those ideas corrupt people.
They might then conclude that there is no hurry to be anywhere in particular other than the place where you are, which in turn would mean that when your time to be Buddhist arrives, you will be Buddhist.
"Being Buddhist" is unimportant. Being moral, including basic regard for other people's situations and acceptance of the duties that arise as a consequence, is however very important.
Until then, you are what you are, and once you become a Buddhist and eventually become some sort of illumined master you would then come to the realization that where you ended is where you began, and the only point in being any at either place and any place in between was simply to be where you were at the moment. Therefore I offer that a truly enlightened master simply wouldn't care what is Buddhist and what is not, because Buddhism is a linguistic tile that cannot apprehend that which you truly are. What you truly are is simply what the universe is doing at the nexus of space and time where you are sitting. It's all you, so who cares what you call it?
All the best

I don't think I can approve of that view, let alone perceive it as genuinely Buddhist. It seems to be at least courting with apathy, callousness and even worse traits.
