Maybe you looked in a different buffer: each buffer has its own notion
of default-directory.

It could, but that would be risky, if you do (start-process "rm -rf
foo") and Emacs decides "oh I can't find the current directory, let's
run this from $HOME instead".
So you have to do it by hand, explicitly.
