I can only confirm it works on zsh 5.0 on Ubuntu. And the /u/lo/b expansion works as well.
You probably didn't turn it on when you ran the config wizard thingy.

What config wizard thingy?
I figured this was a default setting.
ESC+. does not work for me with zsh.
zsh 4.3.11 (i386-apple-darwin12.0)
Maybe it's the version.
ESC+Q also doesn't clear the line.
At the same time, the OP links slide deck fails for me at the cd /u/lo/b part. It simply doesn't work.
