The simplest counter-example is Wikipedia. Most links on any page could lead to generic term definitions, or they could link to explanations of how those terms work withing the context of the page.

I.e. a link to "synthesizers" on a page about FM synthesis could lead to a generic article on synthesizers, or to a list of FM synthesizers released up to date.

And that's just the most obvious example. Having different "linking contexts" would allow to add more links without turning the original document into a mess.

Again, using Wikipedia as an example, you could add another "context" to the page by linking various paragraphs to citations. That would be much more user-friendly than what they do right now with bracketed numbers.
