As an aside, “Nauka” means “Science” in Russian.

Someone explain the physics of this to me. Why is the space station travelling at the same speed as the falling module? Surely the module must have slowed down to fall that far out of orbit, which means the space station would no longer be above it like this?

It is lower, means it is covering less distance to stay under the station, means it is traveling slower.
Think of a slice of pie where the center is the middle of the earth. Space station is at the crust, module say halfway down. Station traveling along the crust must move faster to be even with module in mid slice.
Geometry - its not too late to get it.

Still find it quite mind boggling how fast the ISS moves relative to the clouds.

That is spectacular; however, it must be sobering to be on a space station, watching part of that space station burning up on reentry.

Especially after the new module decided to make unplanned changes to the station’s orientation.
