you cannot use that option, with dasd drives. as dasd drives only support maximum three partitions..... and separate /home /var /tmp and / need 4.
one can use that option on e.g. multipath / zfcp drives; or kvm-qemu virtio drives.
i guess recipes should be modified to guard against offering that option; but do not that this option is not offered by default, have you changed the priority of debconf? Because there are countless paths in low priority d-i for shooting oneself in the foot.
