Yes, that is what that means. Consent is revocable, ongoing, and more complex than, "you were kinda into it before and said yes at first so now I can do whatever I want to you. No takesie backsies." If you ever have sex, yes, that person can change their mind and it is rape if you don't stop. That's right, saying yes to doggystyle doesn't mean they consented to reverse cowgirl and it takes a full two seconds to check in on them throughout sex, y'know, like they're a person. You don't sound like you're talking about common sense like you think you do, you just sound like a fucking rapist who is pissed that consent language is more well known than it used to be.
Unironically, some douche named "LoveCanada" spewing rapist gaslighting talking points is just perfect, could even be a character bit.
