Flight Safety, your comments are very valid. However, the flight control laws of the A320 family do not relate directly to the modes you are referring too.
In those cases, Airbus pilots are advised by a Flight Mode Announciator (FMA) not unlike many other modern jets.
In the case I mentioned, the pilot forcefully held the trim wheel which was automtaically (and correctly) trimming to 0 during the ground roll so I don't think it really falls under the description of "inadvertent contact with a flight control", as you described in your message.
