Can you cite the policy requiring that?

Private ASN are non-unique, and as such pretty much a non-starter in
extranet situations.

I cannot see any language in this document requiring any kind of
"visibility" in any part of whatever network, especially the "Internet".
Can you point us to the specific regulation?

Yes. You seem to mistake "external" with "on the public Internet".
"External" in BGP context is "with other ASN", that's it - not more, not
less.

No.
