Virgin reducing bonus miles?

When I go to:
http://www.virgin-atlantic.com/en/gb/fr ... /index.jsp
The page content is duplicated. The first time is says Silver members get 50% bonus miles and Gold members 100% bonus miles. The second time it says 25% and 50%. Here's a screenshot:

Am I missing something? Do members get different bonus mileage depending on when they signed up or are located?
