[GAMEPLAY] Yasuo gets kill benefits for last hiting with Q an Undead Sion

If Yasuo last hits Sion with a Non-Charged Steel Tempest, it gives Yasuo Gold, Experience and Stacks. (It doesn't score a kill) It only works with the Non Charged Q, nor the E+Q or Tornado Q. It works 100% and it doesn't work with any other spell/ability/item/aa.
