Indeed this is expected behavior. Since there is no way to create a btrfs subvolume in this instance, and you explicitly asked for a btrfs subvolume, it should error. A simple directory copy must be used.
I think it might be reasonable to say that even if it has to do a full directory copy, it could still create a new subvolume so that clones can be done as snapshots.
