If black for example plays on one of the x spots and can establish a ladder breaker here, white would be happy, if he killed the aji. But if the ladder breaker fails to be successful, white feels more happy this way, keeping its ability to make unconditional life in the upper corner.
Because (b)
- withought ladder breaker is not playable
- the ladder breaker might be gote, allowing white to play the exchange later
- even if there is a ladder breaker and black decides to cut, white might decide that it can sacrifice the 2 stones later, just using them as aji to invade the center
- white might be able to form a shape that allows to cut black in a net, or a ladder to the upside later
All these points accounted, I would not account (b) as a strong threat now, while unconditional life in the corner is at least and exchange of 15 sure points in whites favor.
