Yes, correct. I used the word "attitude" loosely but not in reference to what the fbw laws attempt to maintain. To put it straightforwardly, they maintain Nz and roll rate - no input, no change, so attitudes are maintained. IIRC, in Normal or Alt1/2 Laws, a small back pressure on the stick is required to maintain altitude beyond 33deg bank. In Direct, it's a regular airplane and some NU correction is required when banking to change direction.
