How can you know? It is entirely possible that a change in policy will result in all of them hanging within a month. Once you are condemned to death, the only thing between you and the gallows is policy that can be unilaterally changed by whoever decides to carry out the executions or not. The court has spoken, you won't be sentenced again. You are a dead person walking and someone in the executive branch can always decide to let you actually hang. An election of a politician who wants to look tough on crime may result in precisely that.
Tangentially, more than half of the world abolished the death penalty even though terrorism does not spare them. Spain lets Basque butchers live behind bars, so does France with its jihadists.
