Sorry, I'm not quite sure where you're getting your information about what Mail.App does. I'm getting mine from the server telemetry logs where the client first identifies itself as:
"name" "Mac OS X Mail" "version" "7.0 (1816)"
And then proceeds to issue a COPY command:
UID COPY 3360991:3361069 "INBOX.Junk Mail"
See the "COPY" in there. I am the author of the blog post, and I think my credentials in this particular case trump yours, even if you're the author of Mail.App.
