How do I force Kubernetes to re-pull an image?

I have the following replication controller in Kubernetes on GKE:

apiVersion: v1
kind: ReplicationController
metadata:
  name: myapp
  labels:
    app: myapp
spec:
  replicas: 2
  selector:
    app: myapp
    deployment: initial
  template:
    metadata:
      labels:
        app: myapp
        deployment: initial
    spec:
      containers:
      - name: myapp
        image: myregistry.com/myapp:5c3dda6b
        ports:
        - containerPort: 80
      imagePullPolicy: Always
      imagePullSecrets:
        - name: myregistry.com-registry-key

Now, if I say

kubectl rolling-update myapp --image=us.gcr.io/project-107012/myapp:5c3dda6b

the rolling update is performed, but no re-pull. Why?
