I misinterpreted what I was looking at and I made a bad assumption that since the same hash for a known password appeared several times in my narrow view that it was the same for all occurrences of the known password.

Your comment that the maximum number of a given salt||hash was seven also threw me for a second. Am I correct that that is purely coincidental? Given the limit of only two characters for the salt (in what set? all printable characters?) and the sheer volume of accounts there is simply some unintended overlap? It just happens that the most it occured was seven times?
