Could Kavach have prevented the Odisha train accident?

The key features of the Kavach system include automatic brake application in case the locomotive pilot fails to act, the provision of line-side signal display in the cabin for improved visibility in foggy conditions and at higher speeds, continuous updating of movement authority, automatic whistling at level crossings, collision avoidance through direct loco-to-loco communication, and the inclusion of an SOS feature to control trains in emergency situations.
These are the features of kavach . Tell me how it could've prevented accident ? Do kavach records that specific loco has been derailed , hence commnuicate that to locos around it .
Or it just sends data about which track/lane is occupied by it hence which one is free to go/no collision.
Edit- coincidentally tweet above answers my query.
