Yeah, that's correct.  I must have been over-caffeinated when I wrote
that.  Here is the new, hopefully clearer text:

"essentially, the browser enforces a policy that is more strict than
both the policies specified in the meta tag and header, but only strict
enough to correspond to rules in both policies. Any web request that
satisfied both policies alone will be accepted by the new policy, but
any request rejected by either one or both of the two policies will be
rejected."

I also put a kind of formal description following it in the wiki.
