There is a valve in-line in the fuel line.  This valve is what gives the Omnifuel it's wonderful simmering capability (and why the XGK doesn't really simmer).  Now, please show me a valve that can both shut off the fuel and have a cable running through it.  I don't believe that a cable can be run through a valve.  My Omnifuel doesn't have a cable, and I doubt that any Omnifuel does.

Thanks, I figured as such, maybe whoever wrote that got different stoves confused.
The inline valve can be easily removed though to clean the straight pipe and generator. I 
thought maybe the flex pipe could be also removed for cleaning, but it doesn't unscrew.
