Well, it actually gives you the choice -- as I recall the hidden volume feature 
requires that the outer volume be formatted as FAT, so if you need prove that no 
hidden volume exists, formatting the outer volume as NTFS accomplishes this.

Of course, this probably won't help you, because the rubber-hose cryptanalyst 
probably won't follow this explanation and understand the design well enough to 
be convinced.  But still.

And, the hidden volume feature *is* still useful if you actually do have the 
data they're looking for - as you say, it depends on what you're doing.
