Well if you look at the scramble no F or B single turns are ever done, just F2 and B2, so edge orientation is never changed. The scrambles don't ever do that, do they?
first part of the scramble is {R2,B2,F2,U2,L2,D2}.. so it's obvious that that part cannot be F single turns or B single turns... the rest is just whatever is needed to get the wanted position... if the scrambled wants a case where everything is oriented, then it gives you everything oriented, so yet, it is definitely possible to get such scrambles.
