That's right. To avoid the problem you have to understand that
`(with-current-buffer reorder-sentence--buffer ...)` will select the
right buffer but will place point at a location that depends on what was
the last use of that buffer (and redisplay *is* a use of that buffer,
which is why having the buffer displayed makes a difference).
In your case I think you have two options:
1- Take it for granted that the buffer is displayed and make
`reorder-sentence-copy-word-at-point` move the corresponding
window-point (either by selecting that window around the `insert` or
by explicitly using `set-window-point`) and use that window-point as
the insertion point (so the user can move the cursor in that window
in order to insert word either at the end, beginning or elsewhere in
the temp buffer).
2- Use your own notion of "point", e.g. by calling (goto-char <my-point>)
before the `insert` and updating <my-point> as you see fit.
In your example, I suspect using (point-max) for <my-point> might do
the trick.
