Wouldn't that approach result in the sectors being shifted with respect to the index hole vs. the case where the conventional index sensor positions are used? I would imagine that it's a moot point if the disks are being formatted, written and read on the same drive, but I can imagine interoperation issues if you later punch the second jacket window to read/write the disks on an unmodified drive.
