Remember that in Normal Law neutral Sidestick will command roll rate zero. That won’t maintain wings level per se but will oppose any tendency to roll.

in Alternate Law roll control is direct. So if you have any any residual rudder trim, even a tiny amount of asymmetric thrust, or the aircraft isn’t perfectly rigged it will have a tendency to gradually deviate over time.

you might get some better answers if it’s moved this to the “Tech Log” area of this forum.
