Is that an opinion or a research based observation?
Rudder causes yaw,
Yaw redefines effective sweep and span.
Effective sweep creates lift imbalance L-R and thus a rolling moment.
One aileron works on a lengthened arm, the other on a shortened one, both opposing the rolling moment
The kinematics seems not overly complex, but far from "higher speed or slower, the lift increase on control surfaces evens out between the rudder and ailerons"
IDK, just a FBW driver.
