Hi, I'm the first author of the article. Thank you very much for your interest in the method!
For the 2 spheres, it's as you wish ! It depends on where you place the uv system in the CSG tree, if it is above a single sphere then it will remain on it, if it's above the union, the field should extent on both.
The main interest of the method is the fact that the output remains implicit so one can easily plug it in a CSG pipeline.
