Merge Node - ChooseBranch behaviour

Describe the problem

I did not expect that the flow to Input 2 will be executed:

What is the error message (if any)?

No error message - but strange behaviour for me. I did expect that the Node Set2 will not be triggered as it has just an output and no input.

Please share your workflow

Share the output returned by the last node

    "test": {
      "test": "test"
