Note that the sequence field starts at the beginning of the document and numbers through the whole document, based on the identifier you use.
If you are going to have multiple lists in your document, then you can add a second Auto Text entry to help with this.
Thus, you could have several sequences in a single document.
For instance, one numbered sequence could use an identifier of Major Num1, and another use an identifier of Major Num2. You should understand that the sequence field can be much more powerful than implied in this tip.
(A broken numbered list is one in which the flow of the list is interrupted by paragraphs of a different format.) This approach to creating numbered lists is particularly helpful and much less prone to the problems inherent in Word's built-in list numbering.
