[GAMEPLAY] Flying Champions (only tried so far with Talon)

So I was playing an ARAM game as Xin Zhao and I ulted Talon which was supposed to knock him back. But, the Singed on my team flipped him at the same time so Talon disappeared off the map and landed a few feet back. I don't know if this is intentional or not but it would be hard to reproduce so I thought I should report it.
