They are the same pin out. The first data sheet shows a photo with the flat at the top and the drain to the left. The second one shows a line drawing with the flat at the left and the drain at the bottom.
I have in the past seen and used some a far east clones in a plastic TO18 case. You would be much more confused if you found a TO18 one.
I always default to a view with the leads facing my eyes because with a top view the leads would be hidden.
