If a file is designated as 'editorial only', that doesn't necessarily prevent it from being used 'sensitively', e.g. to illustrate an editorial on bedwetting/whatever. (E.g. via iS/Getty, where you don't even need to put 'posed by model' on editorial, from what you quoted). People would need to check all the terms and conditions of each agency they submit to. Also bear in mind that buyers don't always read the rules, and people could have different ideas of what constitutes 'defamatory' or 'sensitive' use.
