It appears like it contains a few other subvolumes:

Even though it doesn't really "contain" them for the purposes of snapshotting,
for deletion you first have to remove all the nested ones.

I believe in recent enough kernels the regular "rmdir" call is able to remove
empty subvolumes, so doing an "rm -rf" on the subvolume you want to remove
will take care of all the nested ones (if any). Or if there's just a couple,
then just remove them manually first.
