How would piebaldism present in monozygotic twins? Would it be on the same spots if both of them have it?

No. The existence of piebaldism is genetic, but the degree and pattern of the affected areas is random. In families who pass down the condition, there is just as much variation between family members as there is between unrelated strangers. Identical twins would not be expected to have any special similarity of affected areas.
