How does the Kailasa Prasthana Sthala of Pujyashri Shankara Bhagavatpadacharya at Kedarnath differ from His Samadhi Sthala in Kanchipuram?

Kedardham is only the Kailasa-prasthana-Sthala of Pujyashri Shankara Bhagavatpadacharya. There is no mention of leaving His mortal coil behind and its burial at that place in the biographies of the Great Acharya. Kedarnath is not the Samadhi-sthala of Pujyasri Sankaracharya.
