Trisrendered is a reliable tool. Blitz culls at the entity level based on the bounding volume. I believe the bounding volume ultimately tested against the view frustum is a bounding box. So you might well not have a cone on screen but it would still be passed for rendering because its bounding box is. This is exagerated by the perspectival projection.
This is an interesting one though because it led me to do some quick tests using orthographic projection mode that seem to indicate that the only culling that occurs in that mode is at near/far which is not something I had noticed before and seems just plain wrong. So Trisrendered is definately doing the trick as an aid to debugging!
