See the W3C Spec: http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-75708506

An HTMLCollection in the HTML DOM is live; it is automatically updated when the underlying document is changed.

A good example of a "dead collection" is the NodeList returned by `querySelectorAll` http://jsfiddle.net/4jyv99o6/14/

Using jQuery is a good example of comparing the behavior of HTMLCollection to a jQuery object http://jsfiddle.net/m3xzdg71/.
