Regarding edge-trailing vs edge-leading I would wonder how it might affect the edge in sharpening, pushing on the most important part of the blade vs. pulling on the most important part of the blade.
One thing for sure metal particles being removed coming off the tip goes along the entire surface with edge-leading.
I think I would prefer edge-trailing for safety only. I would have thought by now someone with machinists skills and tooling skills would have made a rest for the Kalamazoo where you could work free flowing as you can with the Surgi-Sharp type rest.
Personally, in a best case scenario I would want the blade parallel to the ground, if I was standing. My wrist not bent at all, easy on your body. Even if you had to mount the Kalamazoo sander to be oriented so you could obtain a preferred ergonomics. As some professional sharpeners use a similar ergonomic technique with wheels, holding the blade edge flat and placing it at a specific spot on the wheel to obtain the desired angle.
Again with a rest based on same idea as the Surgi-Sharp you can see the edge you are working on and see it’s orientation to the belt. You can SEE what you are doing to the edge where you are working. Also very free flowing where both hands can control the blade, and apply pressure at both ends of the blade.

For Cliff here In this video, his ergonomics are okay sitting where the machine is nearly head high
And here is a video starting around the 19 minute mark that shows a whole lot of pro leading edge work freehand using Burr King....
