The photons are not so much "entangled" as they simply don't bother to have any state until they are held to one in the present. From our biologically evolved and prejudiced perspective, the "past" is set in stone and immutable, so it appears the photons are "entangled." What's actually happening is that in the present where this experiment exists, there is only one past that "explains" the results. But there is also a time-distance where the results of the experiment are lost and the photons are disentangled.
There is no solid past or solid future. A "present" perspective shapes it all.
The origins of our own biological perspective, the perspective that makes it so difficult for us to understand this universe, the perspective that makes subjects like quantum physics, time, or relativity seem so alien and perverse, are pretty clear. Each and every one of us have ancestors "all the way back" to the "beginning of life" who somehow managed to survive and reproduce. What are the "odds" of that, that you would be reading this looking at a picture that "demonstrates" "entanglement" ??? It is clearly a meaningless question.
It is what it is, nothing more, nothing less.
