dear all
cloud anyone help me to understand the image as below.
My questions are 
1. what does the root.cmp mean. does it mean  The root-level tag of every component  <aura:component> ?
Every component inherits the body attribute from <aura:component> so if it means  the aura framework instantiates <aura:component> firstly ?
2.next step the framework will goes through the children of the v.body facet to create each component v.body.
but I can not understand why child.cmp is 2 not parent.cmp or subchild2.cmp ?


thanks in advanced
