I would imagine that several editors are intending for the (as expected in the guidelines) pronouns use to feel so egregious to enough readers that they get angry and complain about it.
All this crap about using ‘her penis’ and so on really hammers home the absurdity of the whole thing. It stops looking like some fluffy ‘be kind’ thing and starts looking like a problem.
Drawing attention to it all is helpful. People realising that they are expected to think ‘she raped the victim with her penis’ is exactly the sort of thing that will provoke a ‘fuck that for a game of soldiers’ response.
