When running the following -
We get only bed, since along the preceding-sibling axis, desk has the same color as bed (brown).
None of the rest has an item along this axis with the same color.
will return the complement set - table,desk,dresser and filing cabinet. BUT not bed.
Returns desk,dresser,bed and filing cabinet. But not the first item - table.
Here, it seems, we compare against white, as we saw above.
I'm not clear about the difference.
Does the = sign in the top one mean belong to the set? If so, why doesn't != bring the complement set.
