It's not the same thing. Let me put it lightly:

Single Target :, , , , -> Not all single target abilities requires a unit to be casted on.

Unit-Targeted : (needs a target to cast, but deals somewhat AoE damage),  (both unit-targeted and single target),  (multiple target damage always),  (both unit-targeted and single target)

You're mixing two concepts that are totally not identicals.
