It does, in a way.

Create a loop file (or an existing partition).
fill it with random data (important!)
cryptsetup luksFormat it
cryptsetup luksOpen it
Format the crypted device with FAT32 (important!)

Then, use loop with a high offset, e.g. more than half of the disk,
create a plain cryptsetup
losetup -o 10000000 device
cryptsetup create loop secretname
format it with any filesystem, copy your very secret documents in it, close
this partition.

By doing this, anyone without the knowledge of the offset + the password
won't be able to prove that you have datas hidden.
Warning, if you write more data in the first luks device than the offset
choosen, you destroy data (but in some case, you may want it).

My 2 cents.
