I checked from FCOM of an airline and I find the procedure is same for all variants. What is the source of your FCOM? Actually Hydraulic failures have simple logic of recovery using redundancies. Green and Yellow through PTU. With PTU loss Yellow through electrical pump. Blue loss is accepted for single failure since it is irreversible. But in dual case blue is recovered through RAT and in case of Green loss Yellow is recovered through Yellow election pump.
