Email clients filter duplicates based on the message id header. When you "reply all", the individual messages sent to all the recipients all have the same message id. A list server _should_ rebroadcast incoming messages with their ids unchanged. A recipient that receives a message directly and also receives a copy from the list *should* see them as duplicates, and a mail client _normally_ should not deliver duplicates. But I think Google Groups is changing the message ids when it broadcasts, with the result that mail clients think the copies from the list are new messages. I don't see duplicates from non-Google-hosted lists even if I am CC'd directly. My opinion is Google's server is misconfigured.
