Sounds like a variant of the old experiment whereby if an atom emits two photons travelling in opposite directions. inducing a change in direction of one photon seemingly instantaneously causes the same change on the other photon yet their rate of separation is 2x the speed of light.
Yes, it proved the EPR conjecture would be true and disproved Einstein’s claim that it could not happen. It has also been proven that no information can be transmitted across this communication channel.
It’s just a multiverse correlation.
