It's quite a different mental model the author has from me.
Cut moves text from the application into a separate application, the clipboard.
So just like if I edit in application A, change to application B and hit undo, I do not expect undo to affect A, I also do not expect undo to affect the pasteboard.
The Ghost Cut works a bit closer to how Excel works, which constantly trips me up. In Excel, I might copy a cell, do some edits, then paste, only to learn that nothing was actually copied. In Excel, copy and cut makes a reference to a selection, and if that selection has been undone or changed at the time of paste, there simply isn't anything to paste.
