That was completely unnecessary and cheapens the scene. His face might be hidden behind a mask, but in the original cut you can clearly see and feel that Vader is struggling with his emotions, memories, etc. without the need to be smashed over the head with a prequel montage. But given George's penchant for screwing with the OT, I wouldn't be the least bit surprised to see something like this on the eventual super Blu-Ray "I swear this is how I originally intended the movies to be" Edition of the films in 2011...
