There are two rollouts above (which will appear side by side, if you widen your window enough). If Blue makes his 3pt with 63 in the first position (lefthand), he reaches the identical position that he reaches if he makes his 3pt with 53 in the second (righthand) position.
If Blue hits, the positions diverge. It is for this reason that on the one hand P (making the 3pt) is tied with or slightly better than X (hit and split) in the first position, while on the other hand X is much better than P in the second position.
I've isolated the key difference in the third position below. Blue has a lone ace to play, and is only permitted to choose between 24/23 and 9/8.
If you can grasp why 9/8 is .053 better than 24/23, your intuition will be in line with Blue being willing to make the 3pt in the first position but being very unwilling to make the 3pt in the second position.
