League of Legends (LoL) Question: Targon gold

Sry for bothering but I am too lazy to test it and I don´t want to ruin a game. The question is on Targons gold passive on ranged supports like Thresh Annie... I thought that they changed Targon on only melee attacks he has it in description but I see Targon in LCS & Challenger series on Thresh and Annie. So how is it ? Ty for answer without hate :-)
