The video is from data taken around September 8, 2020 05:26:17 UTC.
There doesn't seem to be any way to look at historical satellite data on the website.
The guy in the video seems convinced that the DEW is land based, but what he's looking at is a 2D representation of 3D space. To me it looks like the beam is space based and the satellite picture is taken from another angle in space, which on a 2D surface makes the beam appear to come from a different angle.

why aren't there any videos of the 1000s of satellites orbiting the earth?

If you're away from the city, you can see them any night. Just look up for a while.

When looking for satellites, consider the position of the sun. Satellites reflect the sun.

Right. Halfway between sunrise and sunset probably isn't the best time.
