If on the same domain, no. But remember that "external" 
means "links that would have not been downloaded without 
the external option"

If you specified filters, like -*, ALL links will be 
considered "external"

Maybe a clue for this problem?
I also just fixed (RC18-2) a very annoying bug which causes 
filters to be crushed in certain cases.
