I think the bulleted list is a good start but should be simplified by 
saying something like:
1. If the native markup gives precedence to its own implicit semantics, or 
there is no ARIA role, use the native markup to determine the role (if the 
native markup does not provide a role, do not expose one).
2. Otherwise, use the ARIA role

I agree with the logic.

A. some language constructs have implicit properties
(including states and roles in properties, here) regardless whether 
'weak' or 'strong'

B. some of these implicit properties are strong, i.e. take precedence 
over explicit ARIA markup.

I'm not sure how  re-organizing things this way simplifies the WAI- 
ARIA spec.  It's pretty much
how I addressed things.  But I have fiddled the prose to make it read 
more like this. The new
v.3 is at:

I fear that no matter how we describe the two factors, given that the 
explicit ARIA role can
be present or absent and the implicit ARIA role can be strong, weak, 
or absent, we still wind
up with the same five cases in the bullet list in "7.3.2.2.  Overview."
