Indeed it does. And should they have created a bigger problem then the subsequent board of enquiry would have crucified them for not following the QRH checklist properly.
As I said, Boeing cannot be seen to have a checklist that could potentially make the problem worse. If you as the skipper decide to do something off your own back, then so be it. But, as far as Boeing is concerned, you're on your own
Edited to add: I have no idea if the QRH is any different for aircraft with blended winglets. It may be that recycling the flaps is an acceptable procedure.... but I doubt it.
