I don't think it's a bug, per se -- it's just how the code is written.
So far as I can tell, Gnus just calculates what the previous ten (or
however many) articles numbers *would* be, and then requests those
numbers. I haven't stepped through the code to confirm, but that's what
it looks like.

I assume it would be possible to write a generic way of requesting some
number of old articles from a backend, regardless of their actual
article numbers, but my guess is that no one will get to that very soon!
