If someone says, "If I asked you out, what would you say?"

While talking to a guy I met recently, a friend of mine mentioned to him that a different man had asked me out earlier that day. The guy I was talking to wanted to know if I turned the other guy down or not (I had), then asked me what I would say if he asked me out somewhere. I sort of made a joke out of it and didn't answer him directly, because I assumed he wasn't being serious. However, other people I mentioned this conversation to said the only reason he'd ask something like that was if he was interested and was trying to test the waters. Is that true?
