Aparentemente os polígonos fornecidos representam "áreas de roteirização postal", e não necessariamente jurisdições.
Alguns exemplos representativos:
https://osm.codes/UY-AR-Artigas
Fica evidente que foi priorizada a "mancha urbana", deixando de fora o aeroporto, que certamente é também parte do território do município.
https://osm.codes/UY-CA-BarrosBlancos
A adição da "ilha" parece decorrência de traçado de "roteamento postal", muito mais do que delimitação de uma jurisdição consistente.
http://osm.codes/UY-TT-ArroceraQuerencia
Mais uma vez, aparência de "roteamento postal". O polígono tem a área de uma chácara (inferior a 1 km2), não de um município ou jurisdição.
Outra evidência é o tamanho dos polígonos. Abaixo a listagem dos 20 maiores depois dos 20 menores.

(perhaps non-valid for scientific codes - need squares on hexadecimals).
