Syndra Snowdown skin and Talon (was using dragonblade)

So, I'm not sure if the Talon skin is relevant, but I just got done playing a match as Talon vs a Syndra mid. All of her left over spheres where subjecxt to being hit when I cast my W. But they only connected on the way back, granted, it just pinged them as being invulnerable. Not a super big deal, but thought you ought to know.

Thanks!
