It's probably only an accident that Japanese Kumo seems similar to Latin Cumulus.
The * symbol by the way marks what linguists think was the oldest Sinitic form of Modern Yun.
Another possible reconstruction could be hwiang or huan or even hiwan.
But I'm guessing. Not having access to time travel we can only argue for the form that has the highest probablityof being closest to the most ancient forms of Chinese and whatever langauge.
