Answer
They enforce strict ordinal rules; Pod N+1 waits for Pod N to become Ready.
Quick Answer
StatefulSets create Pods in order (app-0, app-1, ...) and each must be Running and Ready before the next is created. They terminate Pods in reverse order (app-2, app-1, app-0). This ordered lifecycle is critical for distributed systems that elect leaders or require peers to join one at a time. The Pod Management Policy can be set to Parallel for workloads that don't need ordering.
