I can't find the video anymore either, but I'll try to explain.
For the first God Hand, back up a tiny bit at the start, and do 214D so that it hits Yu at the height of his jump. Instead of cancelling directly into God Hand like the official demonstration, though, you can get a little extra height on Yu by linking 214D into 2D after he bounces off the wall. 2D will knock Yu even higher and cause another wall bounce. Then finally perform God Hand C just AFTER the second wallbounce. If done correctly, God Hand's hitbox will appear slightly before Yu actually touches it, and Yu will fall into the hitbox. So it's the latest possible moment the attack can hit, combined with the longest time he can spend falling back down to the ground.
This should keep Yu grounded long enough for you to recover and pick him up with 2A for the next super. From here you can combo him however you like, as long as it ends in a One More Burst to knock him high into the air. I used 2A 5C 214C OMB. After the OMB, the same principles apply: wait until Yu is as high as possible (just before he starts falling back down), and input God Hand D. If done correctly Yu will touch the very tip top of the super's hitbox.
If you got this, the last super is cake: 2A -> whatever you want -> God Hand C. I used 2A 2C 214C again.
