Yes, when it comes to the cursor, that is correct.

I just verified that the following recipe (posted in 2016) demonstrates the problem, on NS. (The original recipe from 2014 no longer works, though).
emacs -Q
(setq truncate-partial-width-windows nil)
C-x 3
C-x o
C-u 37 x
Here, the cursor which is in text area blinks, while the part in the fringe doesn't.
Wait until the the cursor stop blinking
C-a
Now, the right fringe contains half a cursor.
