Sion's passive giving kill gold a second time?...

So I was playing on the rift against on the top lane. I hit lvl 6 and then the ennemy gank (wait what the picture isnt changed xD), and they tower dive me. I Q once, and then jukes 's slow dashing/Q trought the minion wave. is taking heavy damage from the tower, so i dash/Q, knocking both of them up and ulting. die, but his new passive make him revives. I recieved the gold for killing him one time. So i try to juke trought minion wave while he is in his ult. A THIS MOMENT, the tower hit and I Q him so he dies for real. Here's the point, I recieved 274g a second time. Is it intented? It happened to me once cause i didnt noticed it any other time in the game ( cause i never killed sion again lol).

Don't forget to upvote so Riot can see it and maybe try to diagnose what is going on with this bug.

For the end of the story, i survived at 3 hp to , i knocked him up again under my tower before he could e away x)

P.S: English isnt my native language so please be comprehensive! :)

Good luck on the field of justice summoners!!!

TL;DR: Sion gives gold both times you kill him
