The nice thing about having two elements is that you can require the
BaseState and StateName attributes, whereas one element would render them
both optional. If re-use of StateName for the base states is desired, then
we lose the ability to explicitly enumerate the names of the base states.

But other than this use of XML, there is no conceptual difference, as far as
I can tell.
