shoulder doubling weave direction

I have seen recreations of shirts with doublings going the same vertical direction, and some with their rings going horizontally, ie: turn the weave 90 degrees. Is either way right or wrong, and would there be any protective advantages for a shoulder doubling being in the different direction?

Thanks!
