Help reading the documentation for Homeassistant

Hi, I'm reading the documentation for set up konnected.io with my Home assistant.

I would like to understand what is the use case of having to switch on the same zone.

(https://help.konnected.io/support/solutions/articles/32000022556-set-up-konnected-in-home-assistant-and-hass-io)  

  switches:
        - zone: out
          name: siren
        - zone: 5
          name: 'Beep Beep'
          momentary: 65
          pause: 55
          repeat: 4  
        - zone: 5
          name: Warning
          momentary: 65
          pause: 55
          repeat: -1

  Thanks and congratulation for this project.
