This is correct with the ABSOLUTE SSA. Not with the RELATIVE one.

I agree, basically. So I guess it is the absolute/relative point which
distinguish between us. The immortality distinction results.
Nevertheless I don't understand you when you say:

I guess you disagree with Q19 of Michael Clive Price's FAQ at
Q19 = "Do worlds differentiate or split?"
