I don't remember that exact line, but I do recall similiar reasoning.
For instance when I was younger, I used to hear things like "does that worldly person care about your relationship with Jehovah?" or "does that associate care about whether you gain everlasting life?"
Actually now that I think about it, I think you hear those "different path/goal" lines a lot in their cousel against marrying "unbelievers".
It's all "us vs. them" stuff and used to convince those that are in to stay away from outside influences.
