I fully agree with your general critique. It is a common bad habit in science to use common words with an uncommon meaning without any explanation. I remember me sitting in a lecture about cryptology and wondering how that "I can prove to know a SECRET without revealing it" is supposed to work. I just did not realize that SECRET just meant "random-looking string" instead of something like "I know where the money is hidden".
If it's a map to the hidden treasure (as in the exact bits of the image of the map) then it's kind of the same thing right?
But yes, the non-uniqueness of expressing similar ideas can make things difficult there.
