I think the most common method is to baste the top/batting/back, then baste down each side as far as your longarm will go, then quilt that area. After rolling, quilt the sides again. If you use a measuring tape each time, you ensure that the width of the quilt remains the same as you roll.
In my opinion, it is not necessary to do as much basting as described in the original post. Plus, so many lines can alter the design of the quilting. The only way I would do that much basting is if I were using a water soluble thread (such as Superior's Vanish) in top and bobbin.
