It is OK. He is a good player with a good BH loop. The FH is simply hitting easy high balls. Notice that he says to keep the paddle vertical but he is really hitting the ball at about 1:30 or 45 degree mark so his swing and paddle angle are more about 45 degree which is good for hitting high balls with lots of tangential motion. Notice that he doesn't say to roll the wrist until AFTER impact. NOT during impact. This is OK. I have no complaints except that he is blasting away at high balls. More instructive would be really looping balls from below net height or even at table height where one can't simply blast away because the ball must be hit up and over the net. Now more skill is required to get the right ratio of spin to speed because too much speed will not give the ball enough time to drop onto the table.
This is so STUPID! Explain how he knows the moment of impact when it takes many milliseconds for the impact to be felt!The sub is off and the caption (インパクト瞬間に被せる/cover at the moment of impact) is different from what's being spoken.
