It does not.


What True Crypt needs is a kill phrase.  You give someone that phrase (or
type it in yourself) and it just starts a military format or adds another
layer of encryption with a randomly generated pass phrase.

Or would that not work?

Normal forensics techniques would get around that by just imaging the
system and using a clean copy for each attempt. I'm not sure how it
would work in the presence of a TPM though since I haven't seen any FDE
that makes use of such a module yet. Guess would be it would hinder it
at least a little if done right.

If the system is logged in when its seized then there are a few DMA type
techniques that can image the whole memory before the machine is turned
off or there are the recent techniques of imaging RAM after a reboot,
this can allow the recovery of passwords/phrases in some circumstances.
