Less about "more advanced."
When creating a new, fixed DMX ecosystem, you can do it easy or you can do it right.
Doing it easy leaves you with a simpler install with less disruption and lower routing and infrastructure costs, but data and fixture response issues and anomalies in the mapping. (See: EPCOT inground install. The fixtures were NOT cheap, but the data transmission structure certainly was.)
Doing it right is more disruptive and expensive, but you are left with a reliable, expandable groundplan that is properly terminated and mapped.
They're definitely doing the latter in this.
