New description:

 port mirror --new pseudoport deletes the distfiles_mirror.db before
 processing each port in the expanded pseudoport, so the end result is
 simply a distfiles_mirror.db with only the last port from the expanded
 pseudoport.

 If it only deleted the file once per run, it would be possible to do:

 port mirror --new installed && portmirror

 to delete all of the distfiles that aren't the current ones for installed
 ports...

 (as is, one can work around this by doing port mirror --new
 some_installed_port && port mirror installed && portmirror)
