To put it in other words, zfs doesn't support rebasing a clone off of a newer snapshot. Otherwise e.g. you could create a clone, snapshot each clone, create two new clones and promote them, and then delete the original snapshot. But what zfs does is re-attach the original snapshot to the promoted clone of the original volume, and it is still the referred base of the other clone.
