I found this out because occasionally I only redeemed 1000 miles from eReward. Because of such I was able to see if a 1000, 1000 and 2000 from eReward cumulated, the last 2000 would trigger the 1000 eqm. Then there is 1000 left for next count. If I redeem a 2000 from eReward, it would add to the prev left 1000 and a 1000 eqm posts immediately.
