Variables per step + yaml anchors

[Paris Apostolopoulos]

variables:
  TEST_VARIABLE: "Hello Test"

pipelines:
  default:
    - step: &build-step
        name: build
        image: maven:3.3.9
        caches:
          - maven
        artifacts:
          - target/yxxxx.jar
        script:
          - mvn clean package
    - step: &dockerize
        name: Dockerize
        image: google/cloud-sdk:alpine
        caches:
          - docker
        services:
          - docker
        script:
          - echo $MASTER_TEST



  branches:
    # merging develop we just build and run tests
    develop: *build-step
    # merging to master we build and we push to the docker registry
    master:
      - step: *build-step
      - step:
          <<: *dockerize
          name: Dockerize master
          variables:
            MASTER_TEST: "Test"

Hello , I am coming from a GitlabCI background - and I was wondering if the above was working - after some trial and error I see it is not.

It seems that defining `variables` on a anchored step does not work . I guess variables on the top are not supported at all correct?
