I saw (but, sorry, can't find again) a video of Mark Inouye from San Francisco Symphony describing this very alternating fingering technique for fast passages like in "Scheherazade". And I also remember in Brass Band back in the 60s using this technique to simulate string tremolos (I think it was in an arrangement of Lalo's "Le Roi d'Ys"). There are probably many techniques that we don't utilize as much as we could.
