No, no. this should be 1-of-2. the 2-of-2 doesn't work here. we exactly need either of the keys unlock the funds. therefore we could track abuses.

When Alice is alive uses her primary account for transactions normally. but she also creates a secondary account linked (with OR logic gate) to her primary account, and gives its security values to her attorney/trusted_person with permission to use the keys of the secondary account when she is dead. if she share her primary account with others, she can't track any abuse of her account, but with 1-of-2, you could simply track the sign of your funds to see which sign get used for a particular transaction.
