This is exactly what you wrote.

Numbers like t_B or t'_A cannot be "simultaneous". Events
like e1 = "B sends back a light signal to A" or e2 = "A receives
this signal" can be.

If this is what you meant, which is likely, then, according
to Einstein-Poincaré *definition* of simultaneity:

e1 and e2 are NOT simultaneous for A (nor for B)

If your definition of simultaneity says so, it is broken. You
even noticed that is broken.

Switch from your asinine definition of simultaneity, which is
broken, to a correct one.
