To the best of my knowledge, "soft updates" are not the basis of a
journalling filesystem.  Instead, it is about when meta data on the
disk is updated vs data on the disk.  If your box crashes (or loses
power) and the disk isn't "clean" at bootup, fsck doesn't have a
transaction log it can use (as you do with journalling filesystems)
and so must check the entire partition.
