The first cast is the same the live one, using passive and casted spheres so that idea of suing the spheres as power points to interact with her other spells is there. Subsequents casts however only use the casted ones. At that time you'll already have around 5-7 spheres so, you'll have plenty of raw material to work with. Besides on live her ultimate passive spheres only serve as a baseline damage for her ultimate. Hardly no one uses a 3 sphere ultimate unless we're talking desperation or a very, very, very low target, but even so you still add a Q cast before firing the ult, so in terms of gameplay the value of her passive spheres is actually very low. Visually after the first ultimate, the passive spheres stop rotating around her and are left on the field and you just keep adding more, refreshing and relaunching.
