Does django serve static files that have been modified after collectstatic?

[DoubleCouponDay]

I noticed that I could not get django to acknowledge changes to any static content that I had applied when invoking os.system("grunt taskname filelocation") after collect static. In your documentation you mention that this manage.py extension command is ok to run after collectstatic. Can you explain how this works?
