I didn't assume.  In both posts he described autoclean's function, but said
he expected autoremove to do it.

Slavek is correct that autoremove shouldn't have uninstalled packages that
were still in use, but I'm wondering if maybe there was a good reason it
thought they were no longer required.  Since you installed Trinity, have you
uninstalled any of the metapackages, but left the packages they installed?
That would make apt-get think the packages they installed were no longer
needed, and autoremove would uninstall them.
