Even if you received an email twice (such as received directly + through a mailing list), it will only show one in the mailbox. In this case we are probably seeing the same thing, although in the Sent folder. So if Al sent the email through SMTP (as may be the case by the presence of X-Google-Smtp-Source), and it timed out and was resent, but it was actually accepted by gmail, it would be a classical email duplication. On the other hand, if he was using gmail webmail UI (the @mail.gmail.com at the Message-ID does not look like a local client), this might have happened between two gmail servers, making it much more interesting.
