Im not convinced on that method. The computer that you are using to log in could break, either due a software or hardware error, due being stolen, due a fire happening or other accidents... then what, it takes more than 10 days to recover and the coins are moved and you are still alive.
The only way to guarantee coins move when you are dead is implanting yourself some sort of heart rate monitoring chip which sends the coins when it goes to 0... of course this is absolutely insane.
So far I would focus on not dying, if I had bitcoins, I wouldn't trust what happened to them if I died, so don't die is the best solution right now.
