Yasuo EQ + Thresh E bugs if used together

At 7 seconds I was going to EQ on Khazix, then E'd and Q didn't go off, i got another Q cooldown, and still had my tornado buff. When Yasuo EQ (with tornado) is cancelled by Thresh E, Yasuo Q gets cooldown, even tho Q doesnt go off. (Tornado buff still remains). The bug can be recreated as seen in the rest of the video.
