Is that normal behavior or should the chain remain on the same sprockets during back pedaling in all gears? I don't think the bike was acting this this way before I took it in, but not 100% sure.

I didn't think the bike chain jumped before getting the work done.


So it's normal for the chain to move to a smaller sprocket during back pedaling in big to big position? My road bike doesn't do that. Just try to determine "normal" behavior for a mtn bike before returning to the shop.
