Acoustic Guitar Construction

I was looking at two sets of plans I'd bought long ago from Georgia Luthier Supply. A 000 set and a 00 set.

The x joint in the 000 is what we most often use and see - each brace notched and then glued as half-laps, basically.

But when I blew up to picture of the 00 x-braces, I saw this - and would like your comments. (A close-up and a larger view attached)

Interesting, maybe he thought the bracing was a bit stiff.

Maybe so, hadn't thought of that.
Reading more closely on a different page of the plans, though, I just spotted this: (Coping one of the braces?)

(I just emailed the pictures to the drawer of the plans and asked the question about half-lap vs coping and tongue/groove)

I have not heard back from the drawer of the plans.

But I do notice a number of you have viewed the thread - any other ideas about that x-joint? Does it look strong enough?

In my view that is an idea doomed to fail. The intersection is supposed to be able to distribute the rocking load equally. Beside a normal X configuration does have TG construction, so that coping makes a weaker joint since there is no load resistance on the top half of the coped brace.

Thanks Ken, that makes sense to me.
Though I've never been the same since seeing this R. Taylor scheme:

As I see it -- the coped feature in the example pictured, with all the torque and flexing that goes on in that area seems placing the weakest point at that location presents a prime spot for a split, of course I could be all wet.
