You nailed it.
Aside from that, your idea is that only single target spells get reflected? What about e.g. shackle/dismember/fiend's grip/flaming lasso? Unstable concoction? Life Break? Nether Strike? Charge of Darkness? Lifedrain? Swap? Manadrain? Reality Rift? Burrowstrike? Any arrow ability? Phantom Strike? Blink Strike? Sunder? Static Link? Soul assumption? Snowball? Double Edge? Duel? Omnislash? Focus Fire? And most importantly: Spell steal?
Minor things: Brain Sap? Grave Chill? Ion Shell? Fatal Bonds? Assassinate? Replicate?
Point is, about a quarter of all single target spells wouldn't make sense to be reflected.
