I don't 100% disagree with the sentiment, but I think in this case the push-in style transitions fit well with a knowledge base wiki in which you (or at least, I) often drill down and pop out of topics.
Though... that particular implementation seems to not handle unwinding the stack very well. And as the classic web2 adage goes, if you think your animation is "just right", knock another 3rd off it at least.
IMO TiddlyWiki[1] is a much better implementation of this UI idea of bite-sized, heavily linked text (card catalog?) with multiple simultaneously visible entries. (No federation and a bizarre storage approach though.)
