Santa Draven Blades don't spin

When using the santa draven skin some instances (i'm 98% sure its after using your E) there is no animation for your axes spinning until you hit a minion or champion. It has occurred at least 4 times (so not very often) but annoys the living crap out of me) I have no video footage as you never can really tell when it will happen but i'm pretty sure it has only happened after using my E.

UPDATE: I found out exactly what causes it WITH game footage. so basically when you have your axes spinning and you press e and w at the SAME time (which i do alot) it causes draven to not have the spinning animation while walking.
