Shaco ult not drawing agro

According to http://leagueoflegends.wikia.com/wiki/Turret

"The closest Zz'Rot Portal item.png Zz'Rot Portal. The closest targetable Trap (e.g. Jack in the Box.png Jack in the Box). The closest enemy Pet (e.g. Summon Tibbers.png Summon Tibbers). An effectively random enemy siege minion or super minion. An effectively random enemy melee minion. An effectively random enemy caster minion. The closest enemy champion to the tower."

Is the priority order.

Walk into tower range > Use ultimate > clone (a pet) doesn't draw aggro, instead Shaco gets it.
