As far as I can see on this video that's no tailstrike at all. They bounced on first touchdown, lost airspeed on the bounce, hence the high pitch and almost having a tailstrike, which lead to a balked / rejected landing.
There is a tendency for pilots to keep increasing pitch in these situations to "save" a hard touchdown. A go around / rejected landing (call it what you want) is often the safest solution though.
