They can't be removed, but they can be blurred.

See the overlay example at ffmpeg.org. https://ffmpeg.org/ffmpeg-filters.html#overlay-1

It could be as simple as:

ffmpeg -i video.mkv -i image.png -filter_complex "overlay=200:100" out.mkv

That puts the overlay image x=200, y=100.

There's no reason you can't download and remove/add logos at the same time.

I already looked at the two videos and it's obvious he removed the logo in the first video (with in-painting techniques) to make the second, where he overlaid a new logo.
