This buffer the arrow resides is easily determined:

  (marker-buffer overlay-arrow-position)

But from what buffer do we get the value of overlay-arrow-position?
We need the value of overlay-arrow-position to figure out which buffer-local
value of overlay-arrow-position (and overlay-arrow-string) we should use.
In other words, which comes first, the chicken or the egg?
