Syndra's backing animation

I have noticed this for a while and thought that someone from riot would have noticed this by now;however, this didn't come true and I wanted to point this out. Whenever you back as Syndra, (The original backing, so on the original Syndra skin and Justicar Syndra skin,) it does this thing where she looks like she is going to land and stay there as usual, but she jumps back up and starts flying again and soon it is to where one second she is flying to she is back to the pose she does. Please can you see if that is just new or a bug,
