OEM could mean they got it from the manufacturer directly, that they bought it from the place where the manufacturer bought it (and it is made to manufacturer specs), or that they bought the old dies and presses from Hyundai and are manufacturing the part for the replacement part market.
With a 10yo car, it could also be that they bought a bunch of NOS (New Old Stock) parts from Hyundai at a cheap price too.
