yeah! (to your point about cis people not noticing) this is something referred to in media studies as a “textual wink,” usually in the context of queer analysis; when the author of the media includes something that looks benign to most audiences but not to a smaller (usually queer) audience it signals for them to pay attention to those aspects of the film and that there’s something else going on thematically, like trinity’s bit about “where that road ends” and morpheus’s “splinter in your mind” etc etc
