If you look at the code, it's pretty simple.

If you set nhexl-point to some integer value and then run (nhexl-jit
(point-min) (+ 30 (point-min))) without enabling the mode, you should
get just two overlays and the problem is already visible there.

I think the trick is to have two consecutive overlays, the first with an
after-string and the second with a before-string.
