Multiple "persist_to_workspace" in the same job - duplicates files

Build Environment

Hello,
I created the following example to illustrate my question.

version: 2.1 # Use 2.1 to enable using orbs and other features.

jobs:
  create-file:
    machine: true
    steps:
      - run: |
          echo "I am first" >> first.txt
          echo "I am second" >> second.txt
          #
          mkdir -p /tmp/one/
          mkdir -p /tmp/two/
          #
          mv first.txt /tmp/one/
          mv second.txt /tmp/two/
      - persist_to_workspace:
          root: /tmp/one/
          paths:
            - first.txt
      - persist_to_workspace:
          root: /tmp/two/
          paths:
            - second.txt
  recover-one:
    machine: true
    steps:
      - attach_workspace:
          at: tmp/one/
      - run: find .

  recover-two:
    machine: true
    steps:
      - attach_workspace:
          at: tmp/two/
      - run: find .

workflows:
  check-file:
    jobs:
      - create-file
      - recover-one:
          requires: [create-file]
      - recover-two:
          requires: [recover-one]

The output from job recover-one:

./tmp
./tmp/one
./tmp/one/first.txt
./tmp/one/second.txt

The output from job recover-two:

./tmp
./tmp/two
./tmp/two/first.txt
./tmp/two/second.txt

Why am I recovering the “second.txt” file in the recover-one job and the “first.txt” file in the recover-two job?

Is it something I’m doing wrong?

Sorry for creating this topic. Only now do I understand how persist_to_workspace and attach_workspace work

If you can erase it.
