I ran into the same issue when implementing P3P on W3C's site. 

As your <EXCLUDE>/us/en/*</EXCLUDE> matches already everything after
/us/en/, the statements about <INCLUDE>/us/en/images/*</INCLUDE> are

The Specification says:
When INCLUDE (and optionally, EXCLUDE) elements are present in a
POLICY-REF element, it means that the policy specified in the about
attribute of the POLICY-REF element applies to all the URIs at the
requested host corresponding to the local-URI(s) matched by any of the
INCLUDEs, but not matched by an EXCLUDE element.[1]

To express, what you want, you might consider writing:
<META xmlns="http://www.w3.org/2001/09/P3Pv1">

by <EXCLUDE>...</EXCLUDE> I mean excluding all the subdirectories of
/us/en/, that have a different policy then policy20020114_main.p3p

Another way is to have a different policy for those entrypoints:


You might want to subscribe to our list www-p3p-policy for further
feedback (send email to  www-p3p-policy-request@w3.org with subscribe
