Azir's Sand soilders bugged

"Arise" Azir summons a Sand Soldier to attack nearby targets for him, replacing his basic attack against targets with the soldiers basic range. Their attacks deal magic damage to enemies in a line. the in game tool tip goes on to say that even if Azir is not in basic attack range the Sand soldier still attacks. My last game was against an Azir support and when he would "W" or Arise the soldier would do 3 things. 1) The norm. attack while Azir is in aa animation. 2) Summons soldier attacks the first target once and the soldier continues to attack even when Azir is not in aa and also running out of range. 3) which blew my mind Azir and the sand soldier were attacking at different intervals. I'm not sure if any of the three are intended but it doesnt seem so. Also on 2 and 3 there is no sound and the dmg is sometimes applied.
