Azir Bug (Yes really - Azir once again x'D)

I found this Bug during testing some Azir builds and I guess this 'feature' is not intended:

The Bug only occurs while Azir has above 2.0 Attack Speed (reached with Nash+Rageblade, but also works with with any other AS Items) and keeps AAing with his soldiers. Than, his Soldiers will NEVER disappear! If you time your W casts based on your AA-CD you can create an infinite amount of soldiers, It's also possible to move and Q as long as you do it between your AAs.

Note: I didn't even use the 'URF'-Mode to achieve this amount os soldiers.
