You are correct. The air vent is required on each wet pipe system.
If we look at the definitions in chapter 3, you have separate systems each floor.

As each floor has a separate control valve, is a means to vent trapped air required on each floor? Or is it only required at the highest level of the building? My thinking is that each floor has a separate fire sprinklers system. Any thoughts?
