Good point
I briefly looked around their website and I didn't see any twin fall arrest
lanyards manufactured by them. If they don't manufacture one, perhaps
whoever made the diagram wasn't familiar with where they should be
connected?

Everywhere in the OSHA regulations that I have found discussions of "fall
arrest", the language is identical to what I quoted. Also remember that
building towers is "construction" work. I can find no steeplejack specific
regulations.
And the bottom line to this discussion is: the LXC Prime Directive- do what
the manufacturer says. MSI, the manufacturer of my fall arrest lanyard and
one of the largest safety equipment suppliers in the US, says to connect it
to the rear (dorsal) D ring.
All of my "modern" climbing gear has a little instruction book sewn to the
webbing. Check your little book and see what it says. I'd be interested if
anyone finds instructions that say to connect it to the front D ring.
