Can we shorthand these 'or' conditions?

reading the documentation on state conditions, which is not very conclusive on the topic, so please let me ask if instead of using

      - condition: or
        conditions:
          - condition: state
            entity_id: light.chair
            state: 'on'
          - condition: state
            entity_id: light.couch
            state: 'on'

we can do:

      - condition: or
        conditions:
          - condition: state
            entity_id:
              - light.chair
              - light.couch
            state: 'on'

or would the bottom options simply be 1 condition, in which both lights have to be ‘on’…
