"The first answer is incorrect. You can restore ANY snapshot, but it will replace your CURRENT STATE with the new snapshot.
In the example above, if you restore Snapshot 2, it will now become your current snapshot so you've essentially created a branch of Snapshot 2 and Snapshot 3 is a different branch of Snapshot of 2 which is now frozen in time unless you restore Snapshot 3 at some point in the future."
