Restricting Multiple Organizations in a Single ODRL

I would like to include an ODRL policy that restricts a list of organizations from distributing a piece of content that they receive. So, I am creating a policy that contains a prohibition for a piece of content, with an action of distribute and two constraints one for each organization. This is syntactically valid (i.e. it validates against the current ODRL XSD). But is this the right way to do it? It is certainly compact...

<?xml version="1.0" encoding="UTF-8"?>
<o:policy
    xmlns:o="http://w3.org/ns/odrl/2/"
    type ="o:set"
    inheritAllowed ="true"
    uid = "{UID}">
    <o:prohibition>
        <o:asset uid="{URN FOR PIECE OF CONTENT}" relation="http://w3.org/ns/odrl/vocab#target" />
        <o:action name="http://w3.org/ns/odrl/vocab#distribute" />
        <o:constraint name="http://w3.org/ns/odrl/vocab#recipient" operator="http://w3.org/ns/odrl/vocab#eq" rightOperand= "{UID FOR ORGANIZATION A}"/>
        <o:constraint name="http://w3.org/ns/odrl/vocab#recipient" operator="http://w3.org/ns/odrl/vocab#eq" rightOperand= "{UID FOR ORGANIZATION B}"/>
    </o:prohibition>
</o:policy>

Thanks, as usual, for your help.

Regards,

Stuart
