well if we just look at the cable we know is terminated, does the cable come into the first drop point and have all 6 pairs terminated. Two of these pairs are used at the first drop and another pair is used at the second drop. Essentially so the cable loops through the first drop and the whole cable continues on its merry way to the second drop. Is that the case?

If it is, you could load balance three pairs at each site/office/building and get increased bandwidth that way.
