The RFC number is less interesting then the ASN; he has a low ASN, which is for backbone nerds a little like getting a very short domain name; the short ones are long since exhausted, so it's like an O.G. indicator.
(An ASN is a BGP4 network number; think of it as an address in the backbone routing network.)
