Yes. Looking at savesym.sty (there is no documentation):
- \origCross is the saved value which is not undefined at the end of
the process.
- \Cross is locally \let to \relax and then globally \let to \origCross
- If \Cross was defined as a command with an option, the process will
fail (cf. letltxmacro in the Oberdiek bundle)
- \expandafter before \global is useless
Hum.
