Using Shaco's Q to dodge Fizz's Ult

I was watching a league vid on youtube and I was reminded of this occurrence. This happened maybe about 3-4 months ago, but I have really good memory recall, and this was a very surprising event, so I can accurately retell what happened exactly:

As a Shaco, I was doing my red on the bottom side jungle by pulling it into the bottom-right side bush. The bush was warded though, because pretty close to smiting it, the enemy Fizz, who was hiding in the the bush that's on the top-right of the red camp, was watching me and threw his ult at this moment. Since I wasn't aware of him, he was able to successfully latch/hook it onto me before I reacted. During those few seconds of delay before the shark came up, I walked to the left a bit, the shark following me of course, smite'd red for the kill and heal, and panic Deceive'd into the up-left direction to hopefully get out of Fizz's vision for a little bit and put as much distance between us while I was knocked up... However! When I Q'd, the shark didn't follow me. I apparently blinked within a very small window of time between the shark coming up, and when the damage/cc is applied. I didn't take any damage from it or get knocked up, and the shark did his rising chomp on nothing but air back in the bottom-right bush. Needless to say, since I was still very healthy, I deemed it fine to turn on the Fizz and got the kill.

At any rate, whether it's a bug or not, I'm too lazy to attempt to recreate this, but if anyone can give their account on such a thing happening or perhaps something similar, or is able to consistently recreate this, that'd be cool to know. It could be that this happening on a Fizz ult is a unique interaction between the two abilities, idk.
