To my knowledge the radios and dishes have enough isolation that H/L match
at a site is not necessary unless you're almost pointing in the
same direction with those dishes (or have a TX frequency at one site
overlapping a RX) . The opposite polarity increases the isolation so you
have even less worry in this case. That H/L match idea is more of a
tendency and to simplify planning than a rule.
