Steve,
If you lookup may in a dictionary you will notice that item 4 is: "shall, must —used in law where the sense, purpose, or policy requires this interpretation."
So it is perfectly reasonable to read that as saying that the pages in an extent can only be assigned to a single object. (Which is how I read it.)
I'm not sure I find that a good definition of "may", though this isn't really law. I think more about "may I have a cup of coffee". This is a question.
In terms of "can be assigned to one object", that speaks to me of a possibility. It is possible. An extent can be assigned to one object. An extent can also be assigned to multiple objects. not the same extent, but any non-specific extent can either be one object or multiple objects.
