What does it mean for a photographer to hit naked light directly on the reflector and reflect it to people?

These are two ways of lighting. The first is to use a reflector to soften the light, resulting in the effect of astigmatism lighting, which will not cause bright shadows, and can also change the direction of lighting, mainly to supplement the light. The second kind of light is background light, in order to illuminate the background. Playing in the corner will not make the light too dead and sharp, but also reflect the layering of the background. Illuminating the background and blurring it can make the environment feel spatial, highlight the layering of the whole picture, and also outline and emphasize the subject. I hope it works for you.
