Keep in mind, this is only theory but I think I have an explanation for how you can get 9 spheres (potentially more):

Her ultimate automatically does 3 spheres worth of damage (the 3 spheres surrounding her are released). This means you need 6 additional spheres for max damage - at max CDR the cooldown on her Q goes down to 1.8 seconds. Since the spheres can stay out for 8 seconds, you can cast roughly 4 spheres before the first sphere you cast expires.

HOWEVER, the champion description mentions that you can use her E to extend the duration of an expiring sphere. I'm not entirely sure how this works but depending on if tethering it refreshes the entire duration of the sphere (the whole 8 seconds) or if it offers only a temporary extension, it could mean she could cast a couple of more spheres if she's quick enough before she ults.

Still just speculation on how this works though.
