Task Volume vs TaskRun PodTemplate Volume

[sunyeongchoi]

I'm curious about the priority of Task's Volume and TaskRun's PodTemplate Volume
My expectation is that podTemplate will have higher priority.
Am I correct in my expectation that podTemplate will have higher priority?

Below are examples TaskRun's PodTemplate Volume and Task's Volume

    volumes:
      - name: my-cache
        persistentVolumeClaim:
          claimName: my-volume-claim

      volumeMounts:
