Nested for loop CSG op produces different output to OpenSCAD #3

module m1(i)
{
    translate([i,0,0])
    cube(8, center = true);
}

for (i = [ 3:5 ]) {
    difference(){
        m1(i);
        sphere(r = 5);
    }
}

Produces a shorter block than in OpenSCAD

function appears to be called 3 times (an echo statement in it is called three times, but i is shown to be always 3), and the resulting jscad is:

function main(){

return CSG.cube({center: [0,0,0],radius: [4,4,4], resolution: 16}).translate([3,0,0]).subtract([CSG.sphere({center: [0,0,0], radius: 5, resolution: 16})]);
};
