Has anyone been able to figure out if the "partial expansion activities" policy on the AF website means that if you transfer say Amex points in June 2018 and then Citi points in June 2019, are both you Amex and Citi points going to expire in 2021 or will the Amex points expire in 2020 and the Citi in 2021 (absent taking a flight)? The account page states "xxx valid until June 2021" which makes me think the former, but that seems inconsistent with the rules as we generally think they are.
