If 2. breaks when you do 3., you roll back to 1. If you rolled back to the one before 1, then the values that 3 emitted may still be in the system, causing it to break. When you do 3, you're really testing 2 and 1 is the fallback. If you did 1 and 2 together, then you can't roll back just 2 on its own.
