You are treating the question as asking the 90th percentile of the payment, given than a nonzero payment was made.

I think I understand now!
Initially I was confused because I thought that if we did account for the times when it pays $0, we would take the integral between 0 and h.
But since we're looking for the 90th percentile of Z, we would start at 2, since the value for that 20% of time between 0 and 2 would be 0, correct?
