View Zoom Zoom Columns 2 Bookmode displays pages incorrectly?

From the menu on down - View => Zoom => Zoom Columns => 2 => Bookmode: displays pages incorrectly/inversely. Is it possible to reverse this book to screen page display to match reality or is this a code inversion error?

I used to write some software in Delphi and I would be willing to try to change this code as a way to start learning freeware coding.
