I think this will do it; in the Smart Mailbox editor:

Mailboxes:
√ Include messages in any submailboxes of this mailbox
   Select the root mailbox from the dropdown menu (e.g., the INBOX of 
your account)

Conditions:
• Click the + to add a condition
• Option-click the same (now) top + button to add another compound 
condition; then (regular) click the second + button to add another 
regular condition within the compound condition you just added.  Make 
them look like this:
√ ALL of the following are true
    √ ALL of the following are true
       √ [Recipient (To, CC, Bcc)] [contains] "Taylor"
       √ [From > Name] [contains] "Taylor"
    √ [From > Name] [does not contain] "Martin"

This will gather all messages that were SENT FROM or RECEIVED BY a 
"Taylor" who's not you.  (Note that any of your messages are not 
included, which may make threading or other display a bit...odd.)

Does this cover your use case?
