Actually, it might have some reason - if I'm reading you right all it's doing is using the words as 16+15 bits (rather than 16+16). Maybe they just need word0 to be positive!

It might be an idea to write the rung-displayer generically, because slight variations will be useful for all sorts of hardware and a logic engine or two.
Shall I put you down for rung-displayer in the Maintainers file? (What's a good name for that module? Rung Instruction Visualization Environment?[*])
