I haven't followed every pattern ever flown, but I have never seen an avalanche put in to a schedule to be flown downwind. Keeping it round with the snap being flown upwind is a real problem. Unless you snap at a high throttle setting, the model will drop in air speed during the snap. Also, if you do an inside snap, which most advanced fliers I see do, the nose is going to drop. Combination of reducing airspeed and dropping nose works when the snap is on the downwind portion of the loop. If it's on the upwind portion it is going to make keeping the loop round much harder. The Advanced Pattern is the first time the flier is being introduced to snaps. Why complicate thing even more? I think it is a very poor choice.

Personally, I think changing the Advanced schedule this cycle is not needed. At the contests I've been to and judged I have not seen an over abundance of the current advanced pattern being flown extremely well. And I have seen very few pilots fly it in both directions. I think a change is unwarranted.
