That is pretty much the problem at most EU airports: flights from UK/IRL (or US) typically arrive in an area where most flights are from unclean origins with no dedicated channel and therefore are end up "polluted" by mixing with pax from those "unclean" origins.
I suspect, though, that the overwhelming majority of BA pax in ZRH will terminate there so the system will work for the majority of ex-LON pax as most ZRH-transiting traffic will typically be on LX.
