But how is svn supposed to know that you mean ^! to be expanded to
^/px/py/pz, and not to some other subfolder of the repository root,
say ^/px/py/pt?

AFAICS there is no context telling svn in which project you are
working (unless you mean that svn should deduce this from the working
copy you're in when executing that command).
