So I have an amazon.com and amazon.in account. The latter one is my main account but the former one I created to redeem a gift card I got from a survey.
Seems more like an artifact of Amazon having enabled global logins late into product development than a "feature" to me.
Are you sure it's two accounts? I am using the same login on two different Amazon sites as well, but I'd call that SSO more so than "two accounts on one email address", since all data is separated by country, but the email and password are the same.
