It's not something I've tried, but from observation it would appear that you
can't _make_ apt get A from X and B from Y if both exist in both mirrors
_but_ if you have multiple mirrors in your sources (it doesn't matter
whether they are mirrors or really different repositories - apt can't tell
the difference) apt will open them up in separate threads (to a default
limit of four threads, iirc). Then it may get the first file from the
first mirror and the second from the second mirror.
This is certainly the behaviour where files are not common to different
repositories, but I think I've also seen fallbacks - where package A was
unavailable from mirror X (because of connection problems) getting it from
However, I think it's moot with regard to having the identical URL specified
twice, because I'm pretty sure apt throws away duplicates.
