I Have to analyze that further...

It's strange, yes. I thought it was probably to prevent 

I found yet another oddity speaking for that theory:

The second bank starts like this:

; Second bank

       ORG $2000

And I think *just* tweaking the pointer wouldn't even 
save any ROM in exchange for sacrificing them 6 bytes of
