I'd reword this to something like:

// Starts getting credentials. The credentials and , in case of an error, the
error code are returned using |callback|.
// The NetworkingPrivateCredentialsGetter implementation should ensure that the
credentials request can be successfully processed even if |this| gets deleted
immediately after calling this method.
// Note that there are no guarantees about the thread on which |callback| is
run. The caller should make sure that the result is processed on the right
thread.

Done.
