Martin profiles their braces to a bullet shape before they are glued to the sound board. You can not achieve a tight lap joint unless you have rectangular braces at the joint. Since they do not have rectangular braces at the joint, the joint is not tight. See the picture below:


Now look at Todd's lap joints. Tight as a frog's bottom!

And now you know why Martin and pretty much all of the big guitar manufacturers use a cloth patch. Some boutique builders use the cloth patch on their guitars in keeping with tradition, but a cloth patch is not nearly as strong as a wood cap like Todd uses.
