Maybe I need to play with it some more to see any errors in logic there.

Hello,
It's true that the Brummel will be locked by the method you describe; the problem is it will only be locked of the load comes on the ends. Try it. If you pull the ends away from each other, the Brummel will lock right up. But if you pull on the standing parts (in this case, the sides of the grommet adjacent to the Brummel) it slides right apart.
This topology was a real puzzle for me, and one of the happiest breakthroughs of my little existence. The solution is in Book 5, and involves unbraiding and rebraiding one of the tails. With a short grommet, the locked Brummel is crucial, as the tails just don't add a reassuring amount of friction.
You are right on about having the tails overlap, with the ideal being complementary tapers, for constant diameter.
Fair leads,
Brion Toss

Could you elaborate on what "Book 5" is? My girlfriend works at a nautical bookstore here in Seattle, and we couldn't find anything of yours that looked like the ticket.

And of course I poured through Apprentice looking for the key...
