There really isn't any difference between the Kally and Viel that would make either one more or less usable in reverse, except that it seems like more people use the Viel horizontally. Edge leading would be more accurate running horizontally, because you can see the space between the spine of the knife and the belt more easily.
It's just a personal preference. Not many people sharpen edge leading on belts, so not many people would really need reverse. Since I only run Kallys vertically, edge trailing, I haven't even thought about reverse.
Reversing switches are usually inexpensive and easy to install, and they can come in handy once in a while for most people. My 2x72s all have reverse, but even in knife making I use it infrequently. Most often I simply use it to clean the belt better.
