Checking the postfix code (postfix-20010228-pl05, yes I know it's old):

/*      split_addr() null-terminates \fIlocalpart\fR at the first
/*      occurrence of the \fIdelimiter\fR character found, and
/*      returns a pointer to the remainder.
/*      Reserved addresses are not split: postmaster, mailer-daemon,
/*      double-bounce. Addresses that begin with owner-, or addresses
/*      that end in -request are not split when the owner_request_special
/*      parameter is set.

Suggests that 'yes' is correct, but....

/*      When an alias exists for recipient \fIname\fR, and an alias
/*      exists for \fIowner-name\fR, the sender address is changed
/*      to \fIowner-name\fR, and the owner delivery attribute is
/*      set accordingly. This feature is disabled with
/*      "owner_request_special = no".

suggests that 'no' is correct.  I think I need to look at a newer
version of postfix.
