Because you didn't sync(1) the filesystem or fsync(2) the directory before you cut the power.

That'll be pure fluke - ext4 delays journal writes on namespace operations just like XFS does. > All the > settings, about mount options are default for my distro.

Be aware, however, that this will kill performance unless you have expensive storage with a large amount of battery backed write cache in front of the disks. There's a good chance it will also cause excessive wear on SSDs due to the frequent journal writes.
