Although it's been stated that Mil Mascaras eliminated himself by diving off the top rope to the outside, he technically wasn't actually eliminated. Mascaras actually goes through the middle of the ropes and onto the ring apron, before climbing to the top of the turnbuckle. Rules state that to be eliminated from the Royal Rumble match, one must go over the top rope and down to the floor, with both feet touching the floor.
