Recycled animation frames in Disney's 1967 'The Jungle Book'

What?! I was just watching this video I saw at Laughing Squid and was surprised to see so many recycled animation frames within The Jungle Book! I've known about this tradition of Disney re-using animation frames from one film to the next, but I never knew they did it several times within the same film! All they did in some places was flip the frame to the other side! Cheating!
