The idea is that when Alice see her photon being u, she knows that whatever she

photon being d, including the bob she could ever manifest herself relatively.
And reciprocally with Bob. It is just that when Alice see u, it means that her
accessible histories will all be consistent with u for her photon and d for
bob’s photon. If Bob sees u to, that will be the same: he knows that he will
meet Alice having seen d. Both possibilities will exist. The Alices seeing u
will access a world with Bob seeing d. The Alice seeing d, will access a world
with Bob seeing u. The same for Bob. Both Alices and Bobs observations will
spread toward each other at the speed of light, or slower, and no physical
influence exist at all.
If there is no physical influence, then why is it limited to light speed?
Because the spreading of the superposition is a local phenomenon.
A local physical phenomenon. "Local" means interactions only occur at
the same spacetime point...all both interactions and spacetime are
physical concepts.. So you've done nothing but say the same thing again
while avoiding the word "physical".
