'ContentResolver takePersistableUriPermission with zero flag. Why?

According to official documentation parameter takeFlags of method of ContentResolver takePersistableUriPermission may be zero. Why?

Also in guide Persist permissions

final int takeFlags = intent.getFlags()
            & (Intent.FLAG_GRANT_READ_URI_PERMISSION
            | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
// Check for the freshest data.
getContentResolver().takePersistableUriPermission(uri, takeFlags);

This code means that intent.getFlags() can return zero and we will take zero permission. So, in this case I must call to user with message "can not take permission" but why it may happen? There is no information.
