Hachel now pretends that tB − tA = t'A − tB can be true or false
depending on the observer.

You are lying.
I do not claim it "now". This is what I have always said for at least 40 years.
Now, yes, obviously I assume it.
The value (tA'-tA) = 2AB/c is the same not only for A and B, but also for all the stationary points of the inertial frame of reference of A and B.
Better, if I change frame of reference it will remain true, by invariance of the transverse speed of light in any frame of reference.
On the other hand the value tB-tA (go) will vary for most observers in R (where A and B are stationary), as will the value tA'-tB (return).
But you cannot understand this, because 1. You are stupid and because 2. because you are tied up with relativistic thoughts all learned, but false.
