X-35 with 3rd Rail - Wall Mount

All of the pictures I am seeing of the Woodworker wall mounted look to be with the X50 set up. I know the 50 has a stronger motor and the rails are bigger so it does not require the 3rd rail. But will there be a problem using an X-35 (with stiffy) when it is wall mounted? Has that version been tested in the vertical position or just the X50?

It will be perfectly fine.
