In my opinion, the Snatch and Clean should be treated the same, with of course a different grip. The mechanics and geometry used to raise the bar (regardless of height) should be similar during both lifts.
During the Snatch, athletes believe the bar should be raised as far as possible overhead before attempting to 'get under the bar' - elite athletes can actually elevate the bar to the same height as their Clean.
The truth is, pulling the bar far enough to drop under it will suffice. This concept makes the movement simpler and helps coaches develop beginner and intermediate lifters.
