At around the 0:15 mark, two overlays come on screen, creating an open column in the middle and two horizontal channels at the top left and bottom right. I noticed that I was seeing both options: yellow lines moving horizontally across the top left, turning into downward-moving red and green, then transforming again to yellow as they "turned the corner" at the bottom channel. I wonder if those horizontal spaces will help you see the yellow.
