2 gauge light controls?

I have my wiring all apart chasing different things. I came across 2 variable resistor switches that seem to be for the same thing. They look like they control the brightness of the lights in the gauges. One is in the upper corner of the gauge panel. One is on the underside of the dash to the left of the steering column. The one in the gauge panel has 2 Y/BK wires ganged together and 2 Orange wires together. The othe has 1 Y/BK and one Orange. Checking the wires they are connected to one another.

Why are there 2 of these variable switches controlling the same circuit?
