If this is a system that groks the meaning of the input text and constructs original text to match, then sure, it could just use non-gendered language. But that seems unlikely - we're probably talking about an engine that just recommends whatever occurs frequently in its corpus (hence the article talking about the team black-listing swear words and so forth). In which case adding gendered pronouns to the list seems reasonable enough, and non-gendered forms will presumably show up regardless (to whatever extent they appear in the corpus).
