> should be made for humans to understand what have changed, how did click influence the UI.

But that's exactly where you fail with bad transition - they make the understanding harder! For example, in your video the file name text/icon is moving from the center to the left, but transition animation is showing it stretching horizontally instead, and nothing re the actual move! This is bad and serves no purpose, just creates visual noise and as though the icon is "floating" for a split second.

> If the animation does not attempt to present the contents during the animation

But your video does present content during the animation! It's just that this content doesn't illustrate the object moving, but an unrelated transformation.

So I just don't understand what you compare here and what you think is better.

> the brain would look for any animation deficiencies, nitpicks.

You still have not given a single example of the alternative where you've exploited the brain to not notice. By the way, white flash is a noticeable deficiency
