That is the 85% chance of the steal plus the 15% chance of getting out. In the 85% chance the steal is successful your expected values of runs is 1.1811. In the 15% chance the steal is successful your expected value of runs is 0.2783. It factors in both possibilities if you attempt a steal.

For a 75% base stealer:

(0.75*1.1811) + (0.25*0.2783)

The break even point is the 70% base stealer;

(0.70*1.1811) + (0.30*0.2783)

That equals .91026 which is almost identical to the .9116 expected runs if you don't attempt the steal.
