I believe the withItems part is correct in this example. It is using withItems with a dict (Map) object. It iterates over the objects keys and is an equivalent of

"withItems": {
  "a": "Hello",
  "b": "world"
}

Example output:

> cat concord.yml
flows:
  default:
    - task: log
      in:
        msg: "${item.key} - ${item.value}"
      withItems:
        a: "Hello"
        b: "world"

> concord run
Starting...
13:14:15.308 [main] a - Hello
13:14:15.310 [main] b - world
...done!

Although we should change call: log to task: log to make the example runnable.

Ok. Maybe you can change that. Thanks.
