No. Those are designed to be unique. There is a counter that gets
incremented whenever a new molecule is created.
This is similar to how atom selections get a new (function) name for each
new selection.
So to write "portable" scripts, you have to capture the molecule id on
creation as the return value of the "mol" command (set mol [mol new
somefile.psf]; mol addfile somefile.pdb $mol) same as with the more
commonly seen "set sel [atomselect top all]".
