Justin.tv employee here.
I want to clear up two things. First, we get more uploaded video than YouTube by about 30% (yes, I am serious) and monitoring all of it is not feasible. Over 150 copyright holders (ex. MLB, ESPN, etc) have access to a tool that lets them instantly remove videos. The request is filed as a DMCA take down notice and processed immediately. We do not take any delay for human processing, it's immediately removed. We could process normal email messages, as other companies do, and take down the videos several hours later. That offers a substandard solution for live content though, so we added this extra level of protection.
Second, the live fingerprinting is a double trigger system. We send our scans to Vobile, who matches it against copyright holders who have allowed us to scan for their content. That is running with Fox and has been tested with the NFL/NBC.
In the screenshot you posted, many, if not all of the rights holders for those broadcasts could choose to remove them instantly.
