What does it mean by "nothing will be removed from the later set of matches" ? what is that documentation trying to say ?

In the explaining globs page from the docs docs say that If any non-negative globs follow a negative, nothing will be removed from the later set of matches.

can somebody explain me what that even means.

Now example is given below that as follows

['scripts/**/*.js', '!scripts/vendor/**', 'scripts/vendor/react.js']

My understanding is that the glob will select all the js files inside the scripts folder, and then will remove all the stuff that is inside the scripts/vendor, and now we are trying to access another file called react.js inside vendor - this should give File not found error because that file has been removed from the current stream already, am I right ? if I want to add that again I will have to do the src all over again.
