I did not see this at all. But there's nothing much to clarify.
There are 3 regions, US, EU and Asia. EU and US have 1 set of rules, and Asia has the other set of rules.
Because Asia is 1 region and US and EU are 2 regions, there is nothing special about which region, if US and Asia had the same rules, Europe would be the odd one out.
7am here, time for sleep :/
