Please could someone explain what is going on here:

Code:
# emerge -upD firefox

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U  ] dev-libs/nss-3.13.4 [3.13.3]
[ebuild     U  ] www-client/firefox-10.0.4 [10.0.3]

# emerge -upD thunderbird

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U  ] dev-libs/nss-3.13.4 [3.13.3]
[ebuild     U  ] mail-client/thunderbird-10.0.4 [10.0.3]

# emerge -upD firefox thunderbird

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U  ] dev-libs/nss-3.13.4 [3.13.3]
[ebuild  N     ] dev-perl/XML-SAX-Base-1.80.0
[ebuild     U  ] dev-perl/XML-SAX-0.990.0 [0.16]
[blocks b      ] <dev-perl/XML-SAX-0.990.0 ("<dev-perl/XML-SAX-0.990.0" is blocking dev-perl/XML-SAX-Base-1.80.0)
[ebuild     U  ] dev-perl/XML-LibXML-1.900.0 [1.70] USE="-test%"
[ebuild     U  ] x11-themes/gnome-icon-theme-3.2.1.2 [3.0.0]
[ebuild     U  ] www-client/firefox-10.0.4 [10.0.3]
[ebuild     U  ] mail-client/thunderbird-10.0.4 [10.0.3]


As you can see, trying to emerge either thunderbird or firefox on their own shows only nss as a dependency to upgrade, whereas, if I ask for both to be emerged then a whole lot of perl XML stuff needs to be upgraded as well. 'emerge -upD thunderbird firefox' gives the same effect, so the order doesn't matter.

I think it's the D switch, although why the combination matters, I don't know. What happens if you emerge -uv thunderbird firefox?
