Index path remains absolute - cannot move files once index is created

1. I have a folder with 20 PDF files
2. I create an index of the PDF files in that folder. The path of the index is C:\something\myindex.pdx
3. I then open one of the files in the folder, do CTL-D, and associate the path of the index with the file
4. I save the file and close it.
5. I then move the folder to a network drive, so the new path of the index is T:\something\myindex.pdx
6. I open the file associated with the Index.

Adobe still shows me the path to the index is C:\something\index.pdx, and I'm expecting the path to the index to be T:\something\index.pdx

All previous versions of Adobe Acrobat allowed the path to the index as relative, yet Acrobat XI retains it as absolute.
