One more attempt at a slight improvement:

IRIs have global scope. Thus, two different appearances of an IRI denote the same resource. Violating this principle constitutes an IRI collision [WEBARCH].

Where “IRI collision” links to http://www.w3.org/TR/webarch/#URI-collision

I prefer this because:

1. It links to a foundational document of web architecture.
2. That document explains quite well what the consequences are.
3. As a side effect, we introduce the useful term “IRI collision” to a wider audience.

(I prefer “denote” over “identify”, for consistency within the Introduction section, but could live with “identify” if I really have to, and also with the “by design” bit.)

We should keep in mind that the entire section is informative, and exists merely to introduce some additional useful terminology, and to give the reader a rough idea how they can actually use RDF to express and interpret information about the world.
