I use the kernel command line option plymouth.debug=stream:/dev/ttyS0.

Exactly, this is a log from the startup session of plymouth.

I'm sorry I didn't make it clear why I think the problem is caused by a startup
session
of plymouth instead of shutdown one. I caught all changes of the kernel
variable fg_console
and all calls to the kernel function set_console(). I've got the following
results:
1) plymouth switches the foreground console from 0th to 6th on a startup;
2) plymouth switches the foreground console from 6th to 0th some time after;
3) Xorg switches the foreground console from 0th to 6th remembering that the
active console is 0th.
4) Xorg switches the foreground console from 6th to 0th on a shutdown since the
0th console was active
when Xorg started.
The strange thing here is that plymouth doesn't attempt to switch consoles on a
shutdown.
May it be a race between a plymouth startup and Xorg shutdown? It seems it is
since
the problem ceased to reproduce when I recreated the installation ISO with
the installer kernel compiled manually from the source package shipped with
Ubuntu 13.04.
