We don't know. I was just pointing out the cover art was different/original.
FWIW, they would not have saved/reused the glass masters, though they might use the same digital files.
FWIW, the formats (audio {u-matics) and visual {printing negative films}) used in the early days of cd production are not used today. It would actually be cheaper to begin anew unless all the early editions were saved on a hard drive somewhere, which I find unlikely but not impossible. The cover scans would be new but the cd masters could be made from a first edition cd.
