My understanding is that technical Illusions tracking system is tied to the retro-reflective mat. The glasses see some LEDs on the mat and use that to determine their position and orientation. So the tracking is limited to the glasses being in view of the mat. If you turn around, you're no longer being tracked.
The Lighthouse system, on the other hand, is a full volume tracking system that can be expanded to cover any volume of space. So I could walk around a room and no matter where I am or where I'm looking, I can determine my location and orientation.

There's a wand PCB and a wand on there too, they aren't part of the marker.)
The tracking marker is also covered in retro-reflective material, but it's not part of the mat itself. Relevant because there are clip-on adapters to turn the castAR goggles from AR to VR, and you don't need the mat for VR.
It may not be the final version, as the tracking system has gone through a few upgrades and tweaks already according to the updates.
That's not a limitation of the hardware; castAR has cameras and IMUs, and it could orient itself via any identifiable reference point, which need not be the mat. So this is more a problem of software than of hardware.
