If Black takes away the outside liberty first, Black wins the capturing race.

Diag.: Eyes that lose liberites (2)

White can make a comparable mistake when moving: the forced 1-2 sequence leaves a single eye liberty. Although White can count the inside liberty at a, Black has two outside liberties and can move: Black wins the fight.
