Correct, the 380 is no different to other airbus types in that respect.
You do 2 loops, as NoD said to start the thing going and then once established in the descent, refine it to what is applicable at the time, i.e. damage or no damage and also MSA considerations. This can include speedbrake and also manual deployment of the masks if the cabin altitude hasn't yet reached 14,000. It is not a mandatory item on the checklist, it is common sense if you suffer an explosive decompression, however if you can catch the cabin alt by expediting a descent then it is not required.
At a certain Middle East A380 operating airline, we also have guidelines for any areas of terrain that are likely to impact on Driftdown and Rapid Descent....
You're right Blowfish, if only they'd done it on 2 engines, mind you having just been a pax on an old version of the EK workhorse, with all the creaking, whining and loud hissing about the IFE not working, you probably wouldn't have heard the door go anyway and the temperature wouldn't have changed much
