What is the reasoning behind connecting a 480 volt neutral to a 120/208 volt neutral on a 75 kVA 3 phase 480 volt transformer fed from a 480 volt 5 wire bus plug?

I don’t understand why someone would connect a 480 volt neutral to a 120/208 volt neutral on a 75 kva 3 phase 480 volt transformer. The 480 volts is coming from a 480 volt 5 wire buss plug. Can you explain that to me?
Both neutral wires should be connected to the same grounding system. That was the wrong answer, please disregard.
Louisiana, huh?
Are you a real electrician, ?
Oh yeah, definitely brings the fire every day!
Do you know what an Autotransformer is?
