The installer will fail to request the remote preseed file (as it'll try to get it through the mirror url). A work around if you still want to define the mirror in the append line (and not in the remote preseed file) is to configure it at preseed/run or at preseed/early_command.
Configuring the mirror at the APPEND line is useful when you want to use a master preseed file from every machine but want to have control when to use cache.
The issue still exist in Ubuntu 14.04 (currently in development), as a side effect if a user decides to use:
mirror/http/proxy=http:// domain. tld:3142 in the APPEND line in a pxe environment, eg.
APPEND priority=critical locale=en_US interface=auto mirror/http/proxy=http:// domain. tld:3142 url=http:// another- domain. tld/ubuntu. preseed initrd= ubuntu/ 1404/i386/ initrd. gz
