No. This key is encrypted with the digest key and this key (from the
digest) is derrived from the passphrase. So you don't need to remember 
the randomly chosen key.

You can compare this with the OpenPGP scheme:

The digest key protects the session key. This key does not encrypt
any data, it's just to encrypt the session key.
