I watched that video around both timestamps and didn't see or hear any mention of LIDAR, only of video.

Exactly: they convert video into a world model representation suitable for 3D exploration and simulation without using LIDAR (except perhaps for scale calibration).

My mistake - I misinterpreted your comment, but after re-reading more carefully, it's clear that the video confirms exactly what you said.
