I don't want to speak for DS but I think his intent is to try to find a game, a variant, or some weird in-game stuff that will diminish the advantage a poker-playing bot would have. Typically it is easier to program a bot to play with a fixed (including mixed) strategy than it is program a bot to take into account in-game information.
If someone exposes Kd7d, the humans can adjust their views on other players' ranges. I am not sure that a bot can do that as easily. In fact, typically a bot does not really have "ranges" for its opponents. It has a set series of pre-programmed strategies based upon the action (the board, etc.).
It is not clear to me that it would be easy to pre-program an entire set of bot strategies which can take into account exposed cards. But, I could be wrong.
