Yes, that's the gist of it it seems. It's meant to elicit support. Most people, including MAA would agree full vaginal or anal intercourse with a child would harm them and not be pleasurable or fun (though I'm not saying it's impossible as they get older). So referring to those sex acts and ignoring mutual masturbation, oral sex, etc. is a big emotional pull.

When you say sodomy, I am assuming you don't mean in the oral context, merely the anal context correct?
