Agreed. But it creates a problem (mathematically speaking) for the computation of component OPR: If you include the surrogate in the design matrix, but the component scores reported in the rankings do not include the surrogate match alliance scores in the surrogate's totals, it skews the data.
This is one of the issues Ed Law strives to address in his scouting database by doing some manipulation of the data, but there's really no totally correct way around this with the data currently available.
