Yeah, I had seen that earlier. "Some time ago" people were able to get the H801-7s during the distribution of T210. The visitation by the Old Mill representative was after the main distribution through the cases, during the 1910 season. These cabinets were used to draw a customer into a product that looked very similar to it, they would not have shipped with cards that looked absolutely nothing like the cabinets. T210 Series 2, 5, and 7 are very closely connected in more ways than one, such as T209-2. Geographically speaking, they were also at the core of the Old Mill factory in Virginia. Those series consist of the Virginia League, Carolina Association, and East Carolina League. It's one piece to the puzzle.
Check out post #9 in the link for the method of distribution of H801-7:

T210-8 tells a very interesting story in relation to T211 and some issues that seem earlier such as Hindu SL. You have to dissect the T210 set in pieces. The pieces tell the story.
