Didn’t see any demonstration of VTOL in that video. I highly doubt that has that capability. If you notice, the only 2 western combat jets that have VSTOL (Harrier & F-35) are both single-engine jets. I think that greatly simplifies the problem of vectoring thrust. 2 engines would never deliver EXACTLY the same thrust, making VSTOL much more difficult.

I believe the Russian YAK, that used to be carried on Russian aviation cruisers, was also a single engine VSTOL strike jet.

The Yak-38 had one Tumansky R-28 V-300 vectored thrust main engine and two Rybinsk RD-38 lift engines mounted behind the pilot. It also had critically short range of only around 800 miles. On the up side it only cost $18 million a copy so you could get ten for the cost of an F-35.
