They never specified what each product gets in licensing. They should specify and word it better for us english speaking folks to better understand but I'll take a stab at it.
What I think the charts saying is, the brand new Aquaero controllers get 2 years of licensing when all the other peripherals for them only come with a 1 year license.
So in your case Rodeo, any license that supersedes the rest will be the chosen license by the system by default. Say if it were to expire and you had purchased a peripheral down the road, that peripherals 1 year license would kick in.
Hope all that makes sense.
