Depends what for and how you want to rely on it. It basically says
that the cursor position inside the window is unknown. The "normal"
redisplay must always calculate some reasonable coordinates and put
them there, otherwise the cursor will not be visible, which is a
display bug. If that is enough for you, then yes, you can rely on it.
