Answer
Posting a Binding object updates Pod status; other schedulers skip already-bound Pods.
Quick Answer
The scheduler uses optimistic binding — it chooses a node and then writes a Binding object to the API server, which validates it against current cluster state. Two schedulers could both choose the same node for the same Pod, but only the first binding write succeeds (the second fails due to the Pod's resourceVersion having changed). The losing scheduler must reschedule that Pod.
