I can kind of get this idea from MW's comment alone, but I was hoping for something a bit more concrete, maybe...

I would put it down to how much work that extra stone is doing. To me, the bottom middle black stone really only serves to split the two white groups. An extra stone there has little potential to make territory and doesn't make it any safer because (with the stone at tengen and an extra stone on the left side as in diagram A) it already has reasonable potential for connecting out globally.

Just my thoughts, before MW explains further. The first diagram ends with black sente, right? While the second seems more intuitive to me, let's look a little further down the line.

Would white really play ? I'm not so sure as it seems heavy. Might white just shut down the black stone instead with something like K4, albeit with aji remaining? After all, white doesn't have to be too concerned with that stone since the corner is still open.

If white doesn't play 2, Black's profit after playing there compensates for the loss of the pincer stone imo. Black is super solid and the corner is no longer open. White still has to spend one more move to kill off the aji in the middle.
