AFAICS RFC 6376 places no restriction on a second signature,
even if it is done by the same organisation. The section
on verification mentions handling multiple signatures
(but, again, with no mention of who the signatures are from).
One good reason might be for known changes to the message.
Otherwise... pointless but not really a problem?
