Quan Chi has been known to use doppelgangers in the past to deceive his enemies and protect himself. This may or may not have been the case here.
That doesn't seem to be the case here, though, IMO.
Raiden specifically told Bo Rai Cho that he needs Quan Chi to be alive, in order to get him to reverse Liu Kang and Kung Lao from being revenants and being restored.
Scorpion killing Quan Chi nullifies that possibility, and the proof is in the end scene where Raiden sends a warning to Liu Kang and Kitana (the NEW rulers of the NetherRealm) that "there are fates worse than death."
Also, if Quan Chi didn't really die, do you think he would just sit back and let Liu Kang and Kitana be the new rulers of the NetherRealm, rather than take that chance to be ruler himself?
