Code confusion in function WatchConfig()

[danielchang-Z]

func (v *Viper) WatchConfig() {
   // ...
   else if filepath.Clean(event.Name) == configFile &&
   event.Op&fsnotify.Remove&fsnotify.Remove != 0 {
       eventsWG.Done()
       return
   }
   // ...
 }

This code segment makes me confused that the event.Op does AND-OPERATION with fsnotify.Remove twice . Is there some special purpose?

This was fixed, as my previous comment @sagikazarmark
