Okay, let's see.  Here is the expression:

($doc_scope!='EFSA' or $doc_scope!='No dissemination')

If $doc_scope is 'EFSA' the first test is false and the second is true.
The result of (false or true) is: true

If $doc_scope is 'No dissemination', the first test is true and the second is
false.
The result of (true or false) is: true
