I am not confusing anything. Nobody said anything about number portability
in the above quote.

Just pointing out that some assumptions about how voice call works is not
true. Nor would it be smart to send traffic to another part of the world
unnecessarily. Local calls stay local even when roaming. Please remember
that signaling and voice is separate in the telco world which is why it
compares poorly with IP. Except for the LISP protocol which does something
similar.
