In simple mechanical stick linkages, is there crosstalk between the aileron and the elevator movement? The background story:

I'm an aviation enthusiast (who has played a lot of sim in his life and will play lots more :D) but I've never actually flown any plane myself, as in, actually used the controls (but I'm planning to make my PPL one day, I've always wanted to have wings :).
I also have an idea in my mind which involves a simply constructed stick control column. 

While looking at some pictures of the mechanical construction of the linkages that translate stick movement to aileron/elevator movement, I've stumbled upon this design analysis of the Mitsubishi A6M3 Zero, a japanese WWII fighter plane.

The bewilderment:

Looking at this drawing of the linkages on the stick,



I was wondering:  

If the stick is rotated exactly and only around the aileron axis (thus describing a pure 2D movement along the surface of a circle, basically, the stick does not rotate around the "bolt" (A) with which it is mounted to the bell crank), it looks to me as if this would inevitably lead to a change in angle on the elevator, since the distance between the point where the push pull rod is linked to the stick (B) and the point where it is linked to the "elevator hinge" (C) and the push pull rod would pull stronger on the elevator (leading to a higher AOA) the further the stick is rotated around the aileron axis.

The question(s):

Does this mean that in aircraft with similar stick mechanisms, the further you rotate the stick to the left or right, the more you would have to push it forward/the less you would have to pull it back in order to not change the pitch of your elevator?[1]

If this is the case, is it a problem or does one intuitively get used to compensating for this "crosstalk"?

[1]: I'm not talking about lowering your AOA the more you bank to avoid stalling. Just imagine you're in a steep bank and push the stick to the side quite far to level your wings. Would you have to push forward so you don't increase your AOA while levelling out?

In almost all cases, there is no intentional-- or discernable-- mechanical coupling between aileron deflection and elevator deflection.  However in the Schleicher Ka-6 sailplane, the mechanical linkage is designed to raise both ailerons a little bit, effectively increasing washout in the wing, when the stick is far aft.  See for example page 3 in this manual.  Some other aircraft may share this unusual feature.  You can imagine why it is desirable to have more washout in a low-airspeed thermal turn than in high-airspeed cruising flight.
