That just means it's a two pitch route - rope drag on elegy is bad enough as it is without your rope going to the back of the roof - and the second pitch had been climbed before. Obviously the answer is go out there and try it smarty pants, but in my minds eye I've never been able to work out why you don't put your heel on on the lip and rock on. Even campussing the pebbles sounds easier than the way the hig did it.
