Did Syndra get a new death animation or is it a bug?

I noticed when playing against a Syndra today, she died by falling to the ground and her arms flailing around before hitting the ground. Usually her arms just stayed still by her legs all the way to the ground but from what I saw, it's like she's trying to stop the fall with her arm but looked awkward doing it.

Is it a new animation or is it a weird animation bug?
