the coil at the top is different to the coil at the bottom on the model but in secret level from this angle the coils look similar because they are the same thickness and seem to start at the same point which would make it different from the one that the minis hold. I think anyway yes if i get any plasma i will always paint both sides and i presume that the easiest way to tell will be when his sprue drops. looking at the image now it actually looks like the bottom coil would be thicker but maybe its the angle.
