I think all intermeshing rotors need to index the blades, less they become intersmashing rotors. One advantage to a coaxial is you can index them wherever it makes sense for aerodynamic or whatever reason, and it won't cause intersmashing.
Conversely, any coax needs some indexing, assuming they use gears with teeth. Now, if the X2 technology uses a transmission like the one in my 1971 Harley golf cart, then indexing would be yesterday's news.
