read KJ's section, Riot wants the turret to shoot at the enemy's last known position. Resetting to the original point is the unintentional behaviour of the turret.
Not commenting if the round should be replayed but this falls under the category of a bad very clearly and this resetting mechanic is not mentioned anywhere in KJ's utility kit.
