To me, different  names on each level -- x0, x1, x2, ... would be clearer 
and preferable, so I would know right off which level something was being 
put at.

This is no different from using differnt iteration variables -- i,j,k; or 
i1, i2, i3; etc -- with nested loops.  In both cases, you can delete the 
unneeded var if you really care and will not be using them again for 
another nested construct.
