nope, they need to be unique... or they SHOULD BE unique (globally
unique).  As more folks interconnect internally (business mergers,
partnerships, things such as this) there will be more clashes on 1918
(raising the evil spectre that is NOT the AC-130, but in fact NAT) and ASN
clashes resulting in fragile internal networks needing an ASN swap-out...
which is devilishly hard so I've heard. (atleast on a large network)

lawYers will always make money... but I'm not sure that 'unadvertised' is
the metric you want to use here. 'unpaid' might be better.
