The way I interpreted the wording was that they were specific, clarificatory applications of the primary criteria to the different situations of different kinds of organisation, neither optional alternatives (since notability established according to the alternate criteria would automatically satisfy the primary criteria) nor optional substitutions. As for the national/international issue, they clearly state that NGOs whose activities are purely local are only notable if they have received national/international coverage. The Circle of Reason has received national (Harvard Pluralism Project) attention for local (Minnesota Secular Bible Study) activities, and also has international activity - groups in other countries. The guidelines state that once notability has been established by independent sources (Harvard Pluralism Project, Star Tribune), primary sources (TCOR website, Dutch Cirkel website etc) can be used to provide information. Distracting readers from sourced evidence for notability is not really a concern; establishment of notability is the 'qualification' for inclusion in Wikipedia, once the topic is so qualified the article should contain all relevant information on the topic that can be cited to reliable sources. The international scope of the organisations obviously relevant information.
