I think bitcoinj serializes the secret bytes for these hierarchies: 0, 0/0, 0/1. All the signing keys are derived on the fly, when needed for signing.
Actually the key you're quoting below should be an extended key. It's the parent of the internal keychain (which is used mostly for change addresses).
