You can have more than one version of a file on a CD. All the versions are
listed up in the ISO 9660 directory in the way you described.
As DOS is not aware of the ;n extension, both files are listed up in the
directory under the same name. When opening such a file, always the first
one is opened, of course. So you cannot take advantage of this multiple
version facility. It was established to keep multiple instances of your
data accessible at the same time.
