hmm, din't think so. In Python that point indicates the end of assignment
baz = "baz"

End of defun is reached with following dedent only.

So the OP's expection seems wrong too:

backward-sexp must reach the beginning of the assigment "baz =..."

BTW in python-mode.el we have py-beginning-of-expression for the OP's want.

Cheers,

Andreas
