This is still a mistake. In technical fields such as this one, words
have a well defined meaning.

What about "private", as defined in RFC1918 ?

No, unless you're ready to violate the standards. RFC3927 (Dynamic
Configuration of IPv4 Link-Local Addresses) explicitly states in chapter
7 "Router Considerations" :
A router MUST NOT forward a packet with an IPv4 Link-Local source or
destination address, irrespective of the router's default route
configuration or routes obtained from dynamic routing protocols.
A router which receives a packet with an IPv4 Link-Local source or
destination address MUST NOT forward the packet. This prevents
forwarding of packets back onto the network segment from which they
originated, or to any other segment.
Note that it says "MUST", not "SHOULD".

What you call "assumptions" is just compliance with the standards.
