Erik:
the total Collector-emitter voltage for any darlington, in any condition (including saturation) is the sum of Vbe of high current transistor plus Vce of low current transistor. You can choose the route, but voltage is the same ;) Darlington scheme implies that both collectors are tied together, and emitter of low current transistor is connected to then base of high current one (plus probably some reistor to get better beta in low currents).
