I think using the term "IRI collision" is a very good idea, though I
think it is also good to explicitly mention inconsistencies or
interoperability problems.  But the phrasing above falls short because
it lacks the word "should" or similar.  As written it is like saying "I
will *definitely* call you tomorrow.  But if I don't . . . ."

I would suggest combining your suggestion with some previously suggested
verbiage:
[[
By design, IRIs have global scope. Thus, two different appearances of an
IRI should denote the same resource. Violating this principle
constitutes an IRI collision [WEBARCH] that might lead to
inconsistencies or interoperability problems.
