Doubt in the PhysicsNeMo framework

Hi PhysicsNeMo users and Developers,
I have a quick question regarding the usage of creating Nodes from Governing equations and Neural network architectures. Does the order of the nodes creation matter?, as in can we do like this?

nodes = net.make_node() + ns.makenodes() 

What is the logic behind having the equation nodes created first before the node creation from the network model? Can someone please shed light on this please?
