Maybe I can shed some light.

Shang Tsung was cursed by the Elder Gods to take souls or else he will rapidly age and die. When Shao Kahn took Shang Tsung's souls, he not only rapidly aged but he turned to dust. If Shang Tsung was to die in general, all his souls would escape his body. The same thing would happen to Sindel. We didn't see it but I'm sure all the souls are out of her body and wherever they went be it the Heavens or Netherrealm.
