Yasuo ult bug

Was in a game the other day. Was playing against a Malphite + Yasuo combo, and i noticed a bug/exploit. If Malphite uses his ult on someone, Yasuo can actually wait for the knock-up to finish, and then press ult and prolongue the duration of the CC. If you didn't understand my point, let me rewind it step by step: 1. Malph ults. He begins traveling at our location. 2. He gets out his 1.5 sec CC, and the animation shows us in the air. 3. The animation shows us landing on the ground. 4. Yasuo ults. He did not Q us, he was at distance, but i was still able to spot him, with no minions around him, so he wasn't able to do something like E+Q into us, no Flash used either. BONUS: For all that didn't know, Hecarim's fear apparently doesn't count as CC, since Yasuo can like cleanse it by pressing R: he was feared (the little Fear icon appeared near his model), and he just disappeared while other enemies were still feared.
