Rich I think it is because supporting the heat shield from the two manifolds meant there had to be two different components, a forward one & a rear one.

Supporting the heat shield independently meant one manifold could be used in either position. Another factor might have been the difficulty of removing the retaining stud if it had become too encrusted with the effects of heat, rust & time.
