Content Examples, ABP not referenced ?

Hello guys.

I was checking again some basics fundamentals on the Content Examples project published by Epic Games Content Examples | Fab

But there’s something I don’t understand and it bothers me. On the map Animation/animation_basics

Every blueprints actually playing animations on the level, don’t have any Animation Blueprint referenced :

So here I really would like to know how come those blueprints are animated ??

If anyone has a clue… I would really like to know.

Thanks.
