Such a wrong take. An animated line instantly brings you focus, and remove any guess work, and unease, when analysing a complex system. And in this example , allow you to instatly replay part of the system in your head. Keep working in the direction.

If you replace the moving green boxes with arrows, you get the same information (specifically, flow direction). And if the goal is to show the order/steps, then the right tool for the job is a sequence diagram [0]. Again, the animations are good for getting attention, but otherwise this is re-inventing the square wheel.
