I tried it, and found a problem with cursor placement and another
assertion violation.

; emacs -q -D  ;; not `-Q' in order to show a message in *scratch*
(setq overlay (make-overlay 1 3))
(overlay-put overlay 'before-string (propertize "BE" 'face 'bold))
(overlay-put overlay 'after-string (propertize "AF" 'display 
                         (propertize "XY" 'face 'underline)))
(put-text-property 1 3 'display "DISP")
;; make sure that the first line is wrapped
M-<

Then the cursor is displayed at a wrong position.

Another assertion violation can be observed by replacing the last
expression with (put-text-property 1 3 'display '(space :width 2))
