Yes, the thread is old, but makes good reading...

We may also surmise that Paarthurnax mercy killed the trapped and suffering Numinex, and absorbed his soul...

We can see the Dragonborn absorbs no power from being near the dragon skull in Dragonreach, and that distance is a non-variable in soul-absorbing (one can kill a dragon in Whiterun, immediately Fast Travel to Markarth, and the soul will catch up in a few seconds), so Numinex's skeleton being scattered wouldn't matter.

Pretty dark, and a little sad...Maybe Parthurnax had to kill Olaf to get the job done, giving the king his death-in-battle.
