Usually because of the above, but it can also be because the web site changes the names of the boxes that you type your details into on every page load, and as Autocomplete works on the basis that it remembers what you typed into a box with the same name on any site, therefore random names means its unlikely (though not impossible) that the details end up appearing on AutoComplete.
