Sunset range condition not behaving as expected

I have an automation which is designed to run between certain times of the day (when the sun comes through a window in my flat) which shuts my automated curtains to block glare on my TV. I have use the sun condition else where when closing the curtains in the evening as this is an easier case. However when I want to shut them in a time range using the sun the logic is a bit more difficult. I also have additional conditions to only shut when sunny or partly cloudy.

I have tweaked this endlessly and I think I have the logic right not but still unsure. In this example I want to shut the curtain in a window of 90 mins prior to 80 mins before sunset. My code exert is below:

alias: Stop TV Glare
description: ''
trigger:
  - platform: state
    entity_id: weather.met_office_xxx
    to: sunny
  - platform: sun
    event: sunset
    offset: '-02:50:00'
  - platform: state
    entity_id: weather.met_office_xxx
    to: partlycloudy
  - platform: device
    device_id: xxx
    domain: media_player
    entity_id: media_player.sony_bravia_tv
    type: turned_on

    conditions:

        conditions:

            after: sunset
            after_offset: '-02:50:00'
          - condition: sun
            before: sunset
            before_offset: '-01:20:00'
      - condition: or
        conditions:
          - condition: state
            entity_id: weather.met_office_xxx
            state: sunny
          - condition: state
            entity_id: weather.met_office_xxx
            state: partlycloudy
  - condition: device
    device_id: xxx
    domain: media_player
    entity_id: media_player.sony_bravia_tv
    type: is_on
action:
  - device_id: xxx
    domain: cover
    entity_id: cover.lounge_curtain_right
    type: set_position
    position: 0
mode: single

I am unsure on the correct syntax for the sun condition, I think AND is correct as I want it to only close in a specific window prior to sunset.

If anyone has something similar or is able to confirm my assumption as I have read the guidance here Conditions - Home Assistant and I think its correct.
