The numbers I posted with a breakdown of each album was from a week or two out of the announcement they hit 1,000,000. It looks to me like they're counting T9X & the Psychumentary in the "1,000,000 soundscans" since they're tracked by Soundscan as Music DVDs.
With those numbers and the updated Killer number, you get 1,006,902 sales. Though, if you take out the two DVDs, you only end up with 984,928 "album" Sales. Thus, I can see where you're coming from.
EDIT: Young Lou deleted his post questioning the numbers, but I'll leave this response since it points out that it looks like they're counting the DVD sales in the total.
As for KayZew, it actually only moved 2,210 units last week.
