I've never clicked with the 'up' part of that que.
I think that cue is designed to help people focus on keeping the quads loaded/active throughout the squat, as it can be easy to shift the tension/load elsewhere. When you flex your quads standing, it looks/feels like pulling your knees up, and obviously standing up from a squat invovles using as much of the muscles involved in knee extension (hi quads) as possible so those quads need to be flexing!
