Unsupported material tends to tearout, veneers even more-so than solids (in general). This is why for cross cuts you see backer boards in play.
Glenn, I think in this case, Jim's reference of top and bottom was referring to the top and bottom of the panel as it is installed in a cabinet, (not the face or backside of the panel), ie; the face side of the panel is UP for the cuts on both edges/sides of a panel because he rotated the panel instead of flipping it over , which accomplishes the "No Chipout" on the face side like you were describing, with both cuts being made with the fence on the right of the blade. (I've probably explained this so it is now really clear as mud).
