Yes, the conical tooth washer needs to be positioned so that the teeth face the hitch. That is what prevents it from coming loose. Take a look at the video I have linked. At about the 1:50 mark the installers start to put the hardware on to mount the hitch and they mention the conical tooth washer.

Whey do the conical washed have teeth? My guess is just to help the customer put them on correctly.
