Wildfire Verdict benign / Action block

I'd like to understand how Wildfire works. I have this example where Verdict is benign and action is block. Why?

@Keny_Schmeling,

What likely happended was the firewall identified the traffic via a signature or local analysis and determined that it was malicious; when it was sent to the wildfire cloud and actually ran in the sandbox environment it was discovered to be benign. Therefore the verdict would report benign, because it is, but the firewall would have blocked the traffic before the file was sent off to be analyzed. 

Now if the hash of the file is seen by your firewall again, it will allow the file as the hash is known to be benign. Likewise, if I attempted to download the same file on my firewall it would also be allowed, because you've already analyzed the file and the hash is known to be benign.
