Restoring the snapshot is what happened to you at every startup. This function is useful if you want to save your current workspace state, browse around and then go back to the state you saved (by taking a snapshot).

You would have gone back to "normal" state if you deleted the current workspace or opened a new one and never took a snapshot.

OW will always open the workspace at startup that was open when you quitted OW. If that workspace was saved (snapshotted) at some point, it will load that snapshot.
