Azure DevOps Pipeline passing variables between jobs

I've been tirelessly trying to make my pipeline work according to the

• Job to job dependencies yaml.
• Troubleshoot pipeline run
• Job to job dependencies context

They claim that if I do the following step I should be able to access Name across multiple jobs:

pool:
  name: ubuntu

parameters:
- name: sourceArtifactPath
  type: string

jobs:
- job: Setup
  steps:
  - script: echo "##vso[task.setvariable variable=Name;isOutput=true]$(basename ${{ parameters.sourceArtifactPath }})"
    name: SetVariables
    displayName: "Set Pipeline Variables"
  - script: echo $(SetVariables.Name)

- job: DoStuff
  dependsOn: Setup
  steps:
  - bash: echo "Important work has beed done"

- job: Upload
  dependsOn: DoStuff
  variables:
    artifactName:  $[ dependencies.Setup.outputs['SetVariables.Name'] ]
  steps:
  - script: echo $(artifactName)
    displayName: "Print Filename"

and it works for the reference inside same job, however when I try to access Setup.SetVariables.Name from different job all im getting is:

==============================================================================
Generating script.
Script contents:
echo 
========================== Starting Command Output ===========================

please help.

some questions look similar but are not exactly the same like:

Here is what worked for me. Important part is isOutput=true. Add this while defining variable otherwise you wont be able to view/print/echo the variable

trigger:
  branches:
    include:
      - 'master'
pool:
  mypool

jobs:
  # Set an output variable from job A
  - job: A
    steps:
    - script: |
        #!/bin/bash        
        echo "##vso[task.setvariable variable=myvar1;isOutput=true]True"
        echo "##vso[task.setvariable variable=myvar2;isOutput=true]hello"
      name: setvarStep
  # Map the variable into job B
  - job: B
    dependsOn: A
    variables:
      myVarFromJobA: $[ dependencies.A.outputs['setvarStep.myvar1'] ]  
      myVarFromJobA1: $[ dependencies.A.outputs['setvarStep.myvar2'] ]  
    steps:
    - script: echo $(myVarFromJobA)
      name: echovar
    - script: echo $(myVarFromJobA1)
      name: echovar1

If you want to reference a variable from the Setup job, you need to declare you're dependent on that job.

- job: Upload
  dependsOn: 
  - Setup
  - DoStuff

It's not enough to declare your job depends on DoStuff which declares its dependency on Setup.
