I'm sorry, you're wrong. On the Airbus fleet the procedure is different. Door status has to be checked against ECAM status before opening since a number of slide deployments were due to false indications on the FAP. The FAP indicated that the doors were disarmed, and I suppose that the disarming process was performed by the cc, but the doors failed to disarm. The result was slide deployment. Consequently, all doors are now crosschecked/doublechecked and well and truly rogered with the flight deck before opening.
Not all unintentional slide deployment is the fault of cabin crew!

OK, just noticed that the thread has dropped the 'easyJet' from its title. The procedures above apply to easyJet, not necessarily all Airbus fleets.
