China's questionable hypersonic missile test

So now it seems China carried out a hypersonic missile test at the end of July as well as in August and, according to the Financial Times, during the earth-orbiting hypersonic trip the Mach 5-plus glide vehicle managed to launch another projectile of some sort before it headed for its target, missing by about 12 miles. What on earth was the objective of this missile within a missile experiment? Very clever if true and certainly the Pentagon seems somewhat aghast at the technology demonstrated by the Chinese. But to what end? Could this extra hidden missie/projectile be a decoy system to fool attempts to shoot down the hypersonic glide vehicle? Possibly. Could it be just another missile with another target in mind? Possible, too, but seems a little silly, especially if the Chinese actually go ahead with having such a weapon careering round the earth during an international crisis - with a nuclear warhead attached. The biggest mystery of all is why Beijing is so intent on having the technology to put a nuclear warhead into low orbit. Is it supposed to be a new type of deterrent to the United States or is it seen as a usable war-winning weapon to force the US to surrender or back off what it was thinking of doing, like going to Taiwan's aid in the event of a Chinese PLA invasion? No one knows what's in Xi Zinping's mind but there is only one conclusion as far as I can see. The Chinese president is playing a very dangerous, even reckless, game here.
