I think it has something to do with persistence of vision like with how we perceive tv and film to be moving, but they’re just rapid stills. In this case your brain is attempting to connect the faces together as one object, but as they flash to different images the size and location of features changes so what you perceive is not the actual face but a morph between them. When you look instead at the faces and not the dot, your conscious mind perceives that the faces are actually different and thus no distortion.
I covered half the screen and looked slightly away from the images on one side and the effect still happens. It doesn’t have to do with the brain trying to connect them.
