Very accurate.  Fragmentation increases exponentially.  The harder it is for the file system to find contiguous space for a file (as the file system gets more and more full) the exponentially worse fragmentation gets.  There's argument on exactly what the cut off point should be -- 90%, 95%, etc -- but by the time your TB file system is that full, you've got more serious problems anyway.

There's several studies on this out there on the web, somewhere.
