So it uses it/she pronouns? Usually the object pronoun is second; does that mean that it wants people to call she "it" unless they're doing something to she? That's off the chain, and sounds like meta-trolling.
The second form is different cases, “he/him”. I have theory that people started using that because they didn’t want to put just “he”. They were following the multiple case form and it stuck. People aren’t really specifying cases because nobody uses different cases and nobody puts cases in the multiple pronouns form.
