Your Geo-Filter is working perfectly. I watched your video, there's absolutely nothing in it that suggests the Geo-Filter isn't working correctly.
Battlefield 4 allows you to choose your server in-game. As such, the Geo-Filter is less useful - the Geo-Filter is meant for games which give you no control over matchmaking.
Even so, at the beginning of the video with Strict Mode enabled and Ping Assist at 0ms, the Geo-Filter correctly blocks all servers outside the radius and gets you a fantastic connection.
When you disable Strict Mode further through the video, you then connect to an American server. This is due to how Battlefield 4 works online, and is nothing to do with the functionality of the Geo-Filter.
I'm glad you're getting fantastic connections when you correctly use the Geo-Filter.
