Can someone explain what this does differently to the status quo under the hood?

Apparently the source code has been lost so probably not

Has any streaming service trained a model to actually understand the music itself to work out what other songs would be of a similar vibe/genre?

My favorite band (vulfpeck, and more recently jack's solo stuff) often branch out into different genres, and it's a bit of whiplash when it goes to another song just because the artists are similar / appear together in other places.
