Because the most natural way to spell it is ":!Documentation/RelNotes"
not ":^:Documentation/RelNotes"?  

And that is why I did not say "invalid way to spell".  It just was
unnecessarily unfamiliar form to say the same thing.

But as you need more than one "prefix" to the real pathname to
trigger the bug in the disambiguation code, :! alone would not have
exhibited the symptom, and you would have needed something
multi-letter like :!: or :!/ in front of that path.
