Dynamic light culling and "freezerendering". How it all works?

**Min Screen Radius for Lights ** sets a minimum radius that lights must affect on the screen to still be visible before they are culled. If the light gets small enough they are culled. lower values make lights stay visible longer even if they only affect a couple of pixels on screen but you still pay the cost for them. Increasing the minimum size they will cull sooner.

But it looks like they cull only if geometry which light are affecting are also culled. Is that right?
In new test project i create single mesh floor, put movable point light and change attenuation radius to 50.
In project setting i change **Min Screen Radius for Lights **to 500.
When i **freezerendering **light are still exist. Even if they are behind my character.
