headCat Position and hudPosition diferences? explanation.

I don't have very clear something: If we are giving a position to catHead and also a position to lifeBar why do we need to give a position to the hud in the gamePlay scene as well? I understand the catHead and lifeBar are inside the hudNode so they need a position inside the hudNode and the hudNode a position on stage. Am I correct? but then why when giving a position to catHead he talks about a position on the screen an not a position of the catHead inside the hudNode? can somebody explain further for me how all this positions work together?
