Rear passenger seat adjustment

[landarcht]

Does anyone know if the seat and lumbar buttons on rear passenger door basically do the same thing? I moved the seat button and the rear back/lumbar button, I didn't notice any difference in movement of the seat and the recline, this is also on a 2013.

My 2011 Equus does the same thing. I don't understand why Hyundai made two different switches operate the same function.
