You'll find a discussion of Jinnaluo in Meat, Wine, and Fighting Monks: Did Shaolin Monks breach Buddhist Dietary Regulations? by Dr. Meir Shahar. Note that in the images, Jinnaluo is depicted with one arm raised characteristically grasping a staff. Many Shaolin forms end in a posture that echoes this. All the traditional Songshan forms do it. Most of the BSL forms do it too. However, it's not strictly a Shaolin pose. If you look at Busted! Kungfu Masters Reveal Their Favorite Military Police Attacks By John Brown and Martha Burr in our 2001 January/February issue, you'll see Sifu Tony Chen doing the same move under the name 'Wu Song strikes the Tiger' out of the O-Mei system.
