Sublime text less component breakdown?

Question

Less

Here a person breaks styles into components in less
works like an atom, his components are not duplicated in css files after deletion
, I can’t do the same in the subline, I constantly duplicate in css,
i.e. I want to include additional styles in parts in the main file , but the subline for all components saves css copies, even if you specify the main file less // main: style.less
does not give anything,
maybe in the sub should it be somehow different ??
