[GAMEPLAY] Azir's soldiers unable to attack when he is far away

The tooltip on Azir's W states that he is able to make the soldier attack even if he himself is not in auto-attack range of the target, but this is not always the case. It seems that when he is relatively far away from the soldier (roughly just outside his own auto-attack range if he were to attack the solder) he cannot order the soldier to attack, even if a minion or champion is within the small range circle around the soldier. I've played a few games with Azir and have been seeing thing pretty consistently. I would place the soldier in a minion wave, move back a bit, but still in the tether range so the soldier lives, and clicking on the minions will do nothing (Azir won't move to attack them, and the soldier won't attack them as well)
