'Conditional or on string comparison not working in block

I have a playbook with a block where I am doing a string comparison on a block like so. Imagine my inventory_hostname is "hello-test.com", in other words this entire block should be skipped.

  - name: Do cool stuff
    block:
      
      - name: Some tasks
        set_fact: feeder="feeder.stuff.com"

      
    when:  ("'hello-prod.com' in inventory_hostname")

If I run it like above, it will skip it. However, If I run it with an or, like below it does not skip it even though inventory_hostname does not match either comparison

  - name: Do cool stuff
    block:
      
      - name: Some tasks
        set_fact: feeder="feeder.stuff.com"

      
    when:  ("'hello-prod.com' in inventory_hostname") or ("'hello-cool-prod.com' in inventory_hostname")

I've never had to use an or before in a when statement, what am I missing?

Your when: clause is actually messing around with quotes and I'm even surprised it does not fire an error. The correct syntax would be:

    when: "'hello-prod.com' in inventory_hostname or 'hello-cool-prod.com' in inventory_hostname"

Meanwhile, you can shorten this condition and get rid off the enclosing double quotes by using the following

    when: inventory_hostname is regex('hello(-cool)?-prod.com')
