No, the reason is that VP contents changes not by TC command but internally. Auto-refresh doesn't work for file system plugins, and FS plugins are fully passive - they can only accept TC commands but can't tell to TC that e.g. panel needs to be updated.I will suppose: due to the using of an external executable.
You may see another refresh bugs with file system plugins, even w/o using external tools. E.g. open same VP folder in both panels and delete a file e.g. in left panel - TC won't refresh right panel.
I can pass refresh command cm_RereadSource to TC but it won't help if another panel is active. And TC have no command cm_RereadTarget yet. And TC will exit archive on reread. So currently VP doesn't send this command at all because of side effects.
