cpp program for calculating a polyhedron's gravity

Run the code on ball_1.obj, and I get "Poly Value : -1.12805", however, when I switch the axes,
const clock_t start = clock(); pos = {{0, x, 0}};
on the 53rd line in poly_run.cpp, the outcome become "Poly Value : -0.728349". It is supposed to be equal because the model is a ball and the mass center is at (0,0,0).
I wonder if there is something wrong.
I guess that you calculate the F_f before you rotate the points to the principle axes, which cause the problem, but I am not sure.
