Multiple entities within a trigger

Configuration
1

When making a trigger for an automation I noticed you can add multiple entities. I am not sure how this works and the documentation seems to be lacking. When I search on Google for multiple entities in a trigger I find fairly old post referring to some blueprints. It seems that this was written when there weren’t multiple entities in a trigger yet.
Can someone explain or refer to a document where it’s explained what it does en how to use it properly? Is it an ‘and’ or ‘or’ function for example.

Say in the following trigger (current_position 0 is closed, 100 is open). does it trigger when 1 of the curtains is not open or when all are not open?

  - trigger: numeric_state
    entity_id:
      - cover.diningroom_curtain
      - cover.livingroom_curtain
      - cover.kitchen_curtain
    attribute: current_position
    above: 95

Hello Utrecht,

That trigger will fire when any one of the entities change from a value less than or equal to 95 to any value above 95.

Automations #1: trigger only fires when it changes from not true to true.
