I think the confusion comes from the difference between what NTFS can do
and what the Win32 (or whatever it's now called) layer allows you to do.
Rumor has it that the old Posix subsystem allowed NTFS to create 2 files
in the same directory that differed only by case.

"Filenames are Case Sensitive on NTFS Volumes"

I realize that for practical purposes, NTFS is seen as case-preserving,
but deep down inside it's case-sensitive.
