I'd have thought this is because definitive maps were compiled at parish level on paper and the identifiers created are based on those paper documents not an IT system. Given that the definitive maps are just that, any sensible digital record should take cognisance of the fact that the same path may be on a parish boundary and therefore a path may have more than one identifier.
As Andy (SomeoneElse) has said there are PRoW which are on the boundary of two counties (The Drift or Sewstern Lane Lincs/Leics is one) so the situation also arises across HAs where there would be no expectation of a common reference system.
