They are not. You're using the http redirector which directed you
to different mirrors with different states of the archive (one has
an old version, another the new one).
This might happen shortly after dinstall runs.

Host is the default. If you want to force sequential downloads,
you'd set access.
Acquire {
Queue-Mode "access";
};
or
Acquire::Queue-Mode "access";
are valid forms.
I wouldn't do it though.

PDiffs are enabled by default.
