{{{
class Appointment(models.Model):
    link = models.ForeignKey(MainData)
    date = models.DateField()

class MainData(models.Model):
    def filteredAppointment1(self):
        return Appointment.objects.filter().latest('date') #my special filter1
    filteredAppointment1.admin_order_field = 'appointment__date'

    def filteredAppointment2(self):
        return Appointment.objects.filter().latest('date') #my special filter2
    filteredAppointment2.admin_order_field = 'appointment__date'
}}}

After sortig it in admin change_list it ends up as a
Cartesian product of [filteredAppointment1 x filteredAppointment2]. Which means: NOT distincted.
