Yep, you are.

Chrome will fill in fields by not just looking at the autocomplete attribute, but also by trying to magically infer it based off the name attribute (and other heuristics).

For example, if you have a text entry box for a filename, and happen to set "name='name'" on it, even with autocomplete off you will get a pick list of people's names.

Interesting, the label for this field is Name, but lucky for me I guess that I gave it a silly name based of the database field it maps to.
