Uhm, no. $PWD only gets updated on cd, not on mv. Thus, the old value is
OK!

This seems wrong. But I'd rather say this is a bug in your shell, not in
the kernel!

/tmp> mkdir old
/tmp> cd old=20
/tmp/old> mv . ../new
/tmp/old> mkdir fff
/tmp/old> ls -al=20

Works for both bash-2.04 and zsh-3.1.9-dev7 (as in Debian unstable).

Well, I can't even reproduce it ;)
