No that is not intended, could you give an example of this?
from ampersand-collection.
If I'm reading this right, I think what you want is https://github.com/AmpersandJS/ampersand-filtered-subcollection
With ampersand-collection
the behavior is this:
var Collection = require('ampersand-collection');
var C = Collection.extend({comparator: 'name'});
var c = new C([{name: 'z'}, {name: 'c'}, {name: 'b'}])
console.log(c.at(0).name, c.at(1).name, c.at(2).name);
// b c z
c.at(2).name = 'a';
console.log(c.at(0).name, c.at(1).name, c.at(2).name);
// b c a
// im assuming you want it to be `a b c`

Oh right, the collection has no way to know if attributes in an object change. So you either set the object wholly, or call sort, I think.

What if we listened to the change:comparator event when the comparator is a string. I think it would make sense for a collection with a comparator to keep itself sorted. If you'd like I can make a pull request.
Ampersand-filtered-subcollection is nice and I use it but I don't want to make a subcollection out of the entire collection for the sake of sorting. Right now I added a change listener to the collection and it works.
