Yes, you are right, longer the rod the farther the piston is away from the counterweight.
That's why the 3.75" internally balanced crankshafts require longer rods, because the counterweights are bigger and you have to move the wrist pin up higher to avoid contact between the piston and the counterweight. Hence the longer rod/higher wrist pin location.
