Why would auto insurance company ask if I have a platinum credit card? Is having one a good or bad thing. I do

I recently applied for an auto insurance quote through AAA insurance. During the questionaire, I was asked whether I have any platinum credit cards. I currently have a car insured through them, and I am concerned whether they could used quote questionair info against me on my current policy. I was trying to get a quote on a new car that I am considering.
