You, of course, won't rely on Volt Switch and U-Turn alone. The whole point about Volt-Turn is maintaining offensive pressure by forcing your opponent to react. Because switching has a higher priority than attacking your opponent either has to stomach the hit or switch out. In the latter case, because of the higher priority of switching, the Volt-Turner keeps the momentum and can react according to the switch-in - at least when you don't Volt Switch into something immune.
