If you watch the replay you can see for yourself.
Now as for the bug, it's not 100% repeatable. The bug is you can spawn your soldiers in walls sometimes, and they can get stuck.
Here's how it looks. I did it by trying to Q a soldier into the wall and then spawning one there. http://puu.sh/iizIk/4a80b2945b.png
