checkout@v2 not getting recent commits

Assume a Github action with two Jobs - job1 & job2

In job1:
Use checkout action to checkout the repo, update any file in the repo, commit and push the changes.

In job2:

Again use checkout action. The repo doesn't contain the commit made in job1.

Here is a replicable sample:

jobs:
  update-version:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - run: |  
          // update file1.txt
          git add file1.txt
          git config --local user.email "github-actions@users.noreply.github.com"
          git config --local user.name "github-actions"
          git commit -m "updated file1"
          git push
        
  deploy:
    needs: update-version
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: cat publish file
      run: |
        # the changes made in job1 are not reflected here
         cat file1.txt

Start with the two-job workflow in the issue body, reproducing the update-version and deploy steps with actions/checkout@v2 and file1.txt. Check the checkout action entry point and its documented behavior around revisions; done means confirming the cause and defining the required code or documentation change.
