Your explanation makes a lot of sense and is therefore probably right. But as someone trained in industrial design I object to the idea that 16-bits is the normal usage and 8-bits is a deviant form (and therefore allows an unusual naming of pins). They should have assumed 8-bits to be the normal usage and have used a0.. to address 8-bits memory and a1.. to address 16-bits memory (as computer designers are used to). But I could be wrong...
