Read what I wrote. "for debugging".

If your code is bug-free, and does what you intend it to do, everything is 
fine. But you wouldn't be doing debugging then, would you?

For debugging, it does _not_ depend on "how you use the file descriptor". 
The whole _point_ is that something does something wrong. Maybe you 
_intended_ to use the file descriptor some way, and the bug was that you 
didn't.
