Many mailing list managers s exclude from distribution recipients who are also listed in To: and Cc:
Many people participate in mailing lists without being subscribed to them (e.g. via Gmane). There is no way for the mailing list to know whether this is the case.
In that case, the recipient doesn't want *any* copies of the message in their email. Which is what they've taken care of by not subscribing their email address to the list.
