It refers to the whole process.
Charger loss, battery heat (another loss), if you look a bit further, wired transmission losses in electricity distribution networks, ...
Adding yet another loss through radiated power transmission, is simply not acceptable.
Aside of the fact of wether or not we even want more high-powered radiation around.
