Why do we care? Well, because more lift means a bigger forward/backward component in the diagram, which means more adverse yaw. If the Spitfire's wing is capable of higher lift than other aircraft (for a given airspeed range, conditions, etc etc) then it will also be prone to more adverse yaw, which means you need to use the rudder more or have oscillations when it goes back to neutral behavior.
I don't know exactly how the Spit's wing compares to other aircraft, so if anyone could shed some light maybe we could track down if this is the cause of the instability. In the case that the Spit wing is better at producing lift then incurring extra instability during rolls would be accurate. There's no such thing as a free lunch in physics.

The Spitfire had Frise ailerons. These are designed so that the aileron on the lower wing in the turn pokes it's nose into the airflow and creates drag, thus to some extent compensating for adverse yaw.
How much tho is another question entirely....
