Perhaps your difficulty stems from a problem with the  
'gimp_channel_combine_masks' PDB function. If executed with replace  
for the op then the result is actually the sum of the two channels. In  
Script-fu:

(gimp-channel-combine-masks dest-channel source-channel  
CHANNEL-OP-REPLACE 0 0)

has the same result as with CHANNEL-OP-ADD. Personally, I would expect  
the dest-channel to be replaced with the source channel, but perhaps I  
am missing something. Regardless, it is an easy work-around.
