They do funnel you into a security recheck but it is a lot better than it used to be. It appears this line is only for those that have cleared C&I. It used to be you had to walk much further and get in security lines for all passengers (both those clearing C&I and all other passengers). It was a zoo. Because the numbers are smaller (C&I only), they apparently don't see the need for a dedicated precheck line (and I tend to agree). However, for those with precheck, they handed us red cards to hand to security so we didn't have to remove shoes, belts, etc. We made it through very quickly. Hope this helps.
