 Technically threads are generally used only for formula groups, which are a 
sufficient number of adjacent cells in a column that use the same formula 
(and get different results because of relative cell addressing). In UI terms, 
write e.g. "=A1*2" to B1, grab the bottom-right corner of the cell and extend 
down. But it's implementated this way because that's usually how large 
spreadsheets are created. So I think it's a needless complication to be 
specific about this.
