Yes - our interpretations are the same.

Subject: Re: Issue 3619 - input from WS-Addressing WG

My apologies, I haven't read Section 3.4 carefully enough and jumped to
the example straight away.
The text clearly states (at least this is how I read it now) is that a
policy which is applied to a subject inside wsp:AppliesTo 
takes precedence over any policies contained inside of the wsp:AppliesTo
element such as EPR.
Asir, can you please confirm this would be equivalent to what you said
in another email in this thread [1] ?

That is, can I conclude that  a policy which is applied to an EPR (using
EPR as an example) inside wsp:AppliesTo overrides/takes 
precedence over an embedded wsp:Policy (directly or in an
embedded or referenced WSDL) and hence no policies reconciliation is
required ?
