The Subdivide operator uses Max's built-in mesh subdivision algorithm, so the results you're seeing are at the mercy of Autodesk's implementation of it - I have no control over the implementation.
You can try using a Weld operator after your Subdivide operator to clean up any un-welded vertices that the Subdivide operator left over.
