Yeah. If you are in ~amd64, why do you want to downgrade systemd?

Yes, sorry.

No, I thought you were in amd64, not ~amd64. If you are in ~amd64,
putting things in /etc/portage/package.keywords should be useless.
Mixing amd64 and ~amd64 is not supported; it usually works if you are
in amd64, and you only keyword some select packages: that's the way I
use GNOME 3.8, soon 3.10, in an otherwise stable system. The other way
around (being ~amd64, and trying to force downgrade of some packages)
sounds rather convoluted to me. I think it would be rather difficult.
You can try; since you are in ~amd64 you *need* to mask the latest
versions of both systemd and virtual/udev, the ones you do not want.
But I would not be surprised if it doesn't work: if *ALL* the system
is ~amd64, the probability of something forcibly pulling the latest
versions of *anything* increases dramatically. The block could be
impossible to solve.
If you are trying to downgrade systemd for the problems related to
GNOME and logind in 206, I'm happy to report that version 207
(available since Sep 14) solves everything; at least in my desktop and
laptop. You should try it.
Regards.
