When Yalda, for example, hands over to the weather, how is she able to name check the presenter? Surely the UK feed and World feed get different weather forecasts and therefore presenters!?

Whenever the presenter name checks the weather presenter near the top of the hour, the World feed has opted out for pre-records, so the UK feed doesn't need a timed outro at :56. 

For example, every weekday at around 1953, the World feed will opt out for their 5-minute Click/Travel Show/Witness History preview. The UK feed will stay with Yalda for a few more domestic stories before Yalda hands over to the weather presenter. No outro is needed during these separate blocks.
