One of the objects (the first link you sent) is the HTTPService object itself.

The second object that wraps the HTTPService object and provides it with additional functionality for the <mxml /> tag.

The two probably have not been merged because you do not necessarily need to implement the IMXMLObject and IMXMLSupport interfaces every time you need an HTTService object.
