FSEvents: kFSEventStreamCreateFlagWatchRoot flag: not getting 'root rename' events

Question

I'm creating FSEvents stream and passing the kFSEventStreamCreateFlagWatchRoot flag. From Apple's documentation:

kFSEventStreamCreateFlagWatchRoot : Request notifications of changes along the path to the path(s) you're watching. For example, with this flag, if you watch "/foo/bar" and it is renamed to "/foo/bar.old", you would receive a RootChanged event. The same is true if the directory "/foo" were renamed. The event you receive is a special event: the path for the event is the original path you specified, the flag kFSEventStreamEventFlagRootChanged is set and event ID is zero.

So when "/foo/bar" renamed to "/foo/bar.old" I'm getting the event as expected. But when "/foo" directory is renamed, I'm not getting the event as I should've. What might be a possible reason?

Is `/foo` a mount point? That is, is it not technically within the device you're monitoring? — Ken Thomases, Jan 01 '19 at 19:36
@KenThomases no. For example it is like "/Users/myUser/Downloads/foo/bar" — Sanich, Jan 02 '19 at 09:01
