Back in the early days of Disney animation, it was not uncommon for animators to cycle animation forward and then backward, repeat action more than once, or use a cross-over technique in which two or more characters do the same action.
From The Illusion of Life:
Sometimes an action could be repeated just as it was in a second scene, but more often a new beginning or a different ending were called for. In these cases, the animator could repeat part of the action by borrowing drawings from the earlier scene. In other cases, there would be an action that could be repeated intact in the same scenes—a character climbing a slippery pole, or sliding down an incline, or being knocked down by a mechanical device.
I remember watching the Disney classics as a kid and thinking some of these scenes are very similar to other Disney movies. I never realized that this type of repeated action was so prominent between films until seeing this YouTube compilation:

Having said that, I don’t considering this to be as big of a cheat as to deserve a flippant “fail” tag so indiscriminately handed out by the Pharisees of the net.
The copying done here, is not tracing, but transferring poses from one character to another, perhaps even from Disney’s large collection of reference footage. As anyone that’s done any animation knows, putting any animation onto a new character is still a very difficult task regardless of where you get the poses.
