Any mail sent out of a sieve script ends up calling the local sendmail 
binary to send the mail.  In the case of postfix of course, sendmail is a 
dummy program to inject messages into postfix's mail queue.

I don't know enough about postfix to directly answer your question, but 
perhaps since sieve is calling sendmail to inject mail into the queue, 
that mail is not subject to the sender_canonical_maps processing that 
occurs over a regular SMTP connection from the user's email client.
