There's a comment stating the intent.

I think the comments make this pretyu clear.  The intent is to avoid
providing listings of acquired objects.  In fact, the intent of both
bits of code, I think is to prevent FTP access to acquired objects.

I suspect that there is a clearer way to implement the intent.
