I added a couple more lines (172, 174) that seem to produce the desired result; I have no idea whether it is optimal, sensible, efficient, scalable, etc.
for i=1 to theMaterials.count do
(
obj_list = (for o in Geometry where o.material == theMaterials[i] collect o)
obj_list_vis = (for o in obj_list where not o.isHidden collect o)
if obj_list.count == 0 do continue
if obj_list_vis.count == 0 do continue
re.addrenderelement (CMasking_Mask())
theelement = re.getrenderelement (re.numrenderelements() - 1 )
theelement.elementName = ("alpha_" + theNames[i] as string)
theelement.nodesMonoOn = true
theelement.nodesMonoIncludeMod= true
theelement.nodesMono = obj_list;
obj_list=#()
--maskEls = append maskEls theelement.elementName
)

/* known issues:
- only Corona materials are renamed to shorten the naming of the saved renderElement
- only poly geometry is supported: lines need to have an editPoly on top of the stack to be recognized; Groups are not supported
- if the "create mono masks" button is pressed several times the script keeps adding new render elements, no check for existing elements at the moment
- open / close script window is somewhat buggy, needs optimizin'...
*/
/* TODO: planed functions (everyone is welcome to change the script in any way / participate in the development ;) )
- check for existing elements and warn the user to create additional or replace the existing once
- delete all mono mask elements
- set different path for render elements
- set different file format for render elements
