Meaning not even a daedric prince could kill him. If anyone else tried to fight alduin, they could sedate him but not defeat him as they cannot absorb his soul. Miraak said he was in full capability of defeating Alduin if he wanted to.

though without Dragonrend I wouldnt see how he would permanently defeat him.
