Correct. This looks to me like a bug in update-exim4.conf

The relevant code in update-exim4.conf starts at line 264.

I think that this issue deserves fixing. I need to ponder a while
whether the fix is possible without breaking things, but probably
documentation in README and/or NEWS may be the only thing possible.
I'd rather not clutter up the debconf templates with that corner-case
information, but would prefer things to Just Work[tm]. Not sure
whether this may be possible.
