If this is a numbered paragraph style, I would expect numbering to continue when it is being reapplied to text later in the same document. List styles, on the other hand, do restart. The safest way to force restarts is to set up a multilevel list (see http://www.shaunakelly.com/word/numb...g20072010.html).

For single-level numbering attached to a paragraph style, no numbering appears to be selected in the Modify Style dialog box when you click Format, Number. This is confusing but it is by design in recent versions of Word.
