[Gameplay] Self targeted Nami Ult

Just tested on practice tool, long range skillshots that can be aimed on the mini-map (ezreal ult, ashe ult, nami ult) can also be "self targeted" by clicking it on the champion portrait, rather than firing towards the cursor it will fire the direction the champion is facing if stationary or backwards if the champion is moving.

Is this a bug? Not sure, but it seems odd for these skills to behave like this, and it has caused me more than once to fire a Nami ult completely opposite the direction I wanted.
