Function ls_files_any 

pub fn ls_files_any(
    root: &Path,
    pathspecs: &[&str],
) -> Result<Vec<String>, Error>

Tracked files under root matching any of several pathspecs, repository-relative, in the byte order the index keeps them in — one subprocess, one pass, each file once.

Asking per pathspec and concatenating would give neither: a file two pathspecs both select would appear twice, and the order would be the caller’s rather than git’s. A hash taken over the result depends on both, which is why this exists as its own call.
