I believe you can r-click the image to open it in its full size to see it better.
Using the same $2 pay-out, it would break down into a dollar worth of SBD and a dollar worth of SP. However, when you sell that 1 SBD, you can buy 6 Steem with it! 6 Steem converted to SP = 6 SP. Plus the one SP given as SP, grants you a total of 7 SP for your $2 earning!

Not all that long ago we saw something like this when the SBD was worth several times what Steem was worth. I believe it was 5x or something close to that. It only stayed that way for a few hours and then receded over a number of days.
