This second option doesn’t buy you a greater overall measure. Or, in other words, if you’re inside a branch, it doesn’t increase your probability of survival. But it does increase the probability that at least one branch will survive (For instance, if the probability of x-risk is 50%, it increases it from 50% to 75%).
My intuitions don’t tell me to care about the probability that at least one branch survives.
