I think the rule of not crosscutting using the rip fence comes more into play when the piece between the blade and the fence is wider than it is long (i.e. think about crosscutting 6” off the end of a 2×4). The way Marc does it is the same way I did it and in my opinion it is safe as long as you pay attention to what you’re doing.

As far as using a crosscut sled, I think that would also be safe, but as you said, I think I would feel safer using the method Marc used when the panel starts to get narrower.

EDIT: If you can get the panel to fit between the front of the miter gauge and the blade, the safest method would probably be to use the miter gauge to guide the workpiece in conjunction with a stop block clamped to the rip fence well in front of the blade to register the panel against for controlling the width of the cut. That way there is no chance that the offcut can become trapped between the fence and the blade.
