Agreed. Need to cut back on right rudder trim as throttle is pulled back.
So, Spit is yawing to the right as throttle is closed.

IF the spitfire's horizontal stabilator creates a positive lift, when i reduce the throttle, the force pushing the tail UP is reduced and it should indeed result in nose up situation (because the force that used to lift tail up has now decreased). But because reducing throttle causes airspeed to drop too, the plane will lose lift too so that could be the simplified reason why it is either ~stable or even noses up.

Is this what "Pocked Sized" tried to explain? am i on a right track here?
Precisely. The low mounted wing and radiators probably add to it as well.
