Had Clement written (7)r6c5,r8c1,r7c8 , then I would insist that it's referring to the truth of 7 somewhere in that set. Had he written either
(7r6c5)(7r8c1)(7r7c8) or (7r6c5)&(7r8c1)&(7r7c8), then it would refer to the truth of 7 in all three cells. As it was written is ambiguous to me.
I think I now understand what you mean. If we say (7)r6c1 = r123c1 then OR is naturally implied within the cell group (because nothing else is possible), and I guess you're arguing that the same interpretation should be used if commas are used to group cells. I guess I must agree and thank you for clearing up some misconceptions I might have had
Then again, I'm still certain that I've seen that other use for commas mentioned somewhere (but it doesn't apply here anyway, and perhaps it's non-standard or obsolete, I don't know).
