Other people with skillshots that have a duration can cancel their skillshots. See Vi, Varus, Zac, etc.

If you cast it and totally wiff, you still wasted the mana and the cooldown. Cancelling just reduces the cooldown that you can't effect with CDR (the duration of the shield is functionally identical to a longer cooldown that starts on-cast, since you can't cancel. Except this CD is immune to CDR and gets longer with each rank in the ability.)
