Question about case statements - When you have multiple case statements, such as

Case
WHEN year > 2000 THEN ‘2000s’
WHEN year > 1990 THEN ‘90s’
ELSE ‘Older’
END AS ‘Decades’
FROM movies;

Does the second WHEN clause only included records that were not captured by the first WHEN clause, so that you don’t have movies from 2008 showing up labeled as 90’s? If not, is there a way to do that?
