ELI5: Does a restaurant really lose a star (or a "grade" in general) when the chef that founded it dies?

I was watching Ratatouille and in the beginning it said something like "And the death of Gusteau (the name of the chef), following tradition, made the restaurant lose another star".

Couldn't find anything on the internet about it.

Yes,

Michelin star are based on a trio:

- owner
- chef
- location

Any change in the three will lead the restaurant to loose its stars.

this is quite logical, the stars are allocated not only on the food (the chef) but also the ambiance/design/view (location) and the staff (management/owner), if any of them change therefore the criteria used to allow the stars need to be re evaluated, that also stop any chains to buy their way into the a star rated restaurant quickly, you buy a three stars restaurant because you are mac Donald ? sure now its a zero stars and will stay that way for 1 year, if you change the staff you will have a hard time to get back your stars, so basically its a protection agaisnt buying a reputation without deserving it.
